-# How to contribute
-
-Note: contributing implies licensing those contributions
-under the terms of [COPYING](COPYING), which is an MIT-like license.
-
-## Opening issues
-
-* Make sure you have a [GitHub account](https://github.com/signup/free)
-* Make sure there is no open issue on the topic
-* [Submit a new issue](https://github.com/NixOS/nixpkgs/issues/new/choose) by choosing the kind of topic and fill out the template
-
-## Submitting changes
-
-Read the ["Submitting changes"](https://nixos.org/nixpkgs/manual/#chap-submitting-changes) section of the nixpkgs manual. It explains how to write, test, and iterate on your change, and which branch to base your pull request against.
-
-Below is a short excerpt of some points in there:
-
-* Format the commit messages in the following way:
-
-  ```
-  (pkg-name | nixos/<module>): (from -> to | init at version | refactor | etc)
-
-  (Motivation for change. Link to release notes. Additional information.)
-  ```
-
-  For consistency, there should not be a period at the end of the commit message's summary line (the first line of the commit message).
-
-  Examples:
-
-  * nginx: init at 2.0.1
-  * firefox: 54.0.1 -> 55.0
-    https://www.mozilla.org/en-US/firefox/55.0/releasenotes/
-  * nixos/hydra: add bazBaz option
-
-    Dual baz behavior is needed to do foo.
-  * nixos/nginx: refactor config generation
-
-    The old config generation system used impure shell scripts and could break in specific circumstances (see #1234).
-
-* `meta.description` should:
-  * Be short, just one sentence.
-  * Be capitalized.
-  * Not start with the package name.
-    * More generally, it should not refer to the package name.
-  * Not end with a period (or any punctuation for that matter).
-  * Aim to inform while avoiding subjective language.
-* `meta.license` must be set and fit the upstream license.
-  * If there is no upstream license, `meta.license` should default to `lib.licenses.unfree`.
-  * If in doubt, try to contact the upstream developers for clarification.
-* `meta.maintainers` must be set.
-
-See the nixpkgs manual for more details on [standard meta-attributes](https://nixos.org/nixpkgs/manual/#sec-standard-meta-attributes).
-
-## Writing good commit messages
-
-In addition to writing properly formatted commit messages, it's important to include relevant information so other developers can later understand *why* a change was made. While this information usually can be found by digging code, mailing list/Discourse archives, pull request discussions or upstream changes, it may require a lot of work.
-
-Package version upgrades usually allow for simpler commit messages, including attribute name, old and new version, as well as a reference to the relevant release notes/changelog. Every once in a while a package upgrade requires more extensive changes, and that subsequently warrants a more verbose message.
-
-Pull requests should not be squash merged in order to keep complete commit messages and GPG signatures intact and must not be when the change doesn't make sense as a single commit.
-This means that, when addressing review comments in order to keep the pull request in an always mergeable status, you will sometimes need to rewrite your branch's history and then force-push it with `git push --force-with-lease`.
-Useful git commands that can help a lot with this are `git commit --patch --amend` and `git rebase --interactive`. For more details consult the git man pages or online resources like [git-rebase.io](https://git-rebase.io/) or [The Pro Git Book](https://git-scm.com/book/en/v2/Git-Tools-Rewriting-History).
-
-## Testing changes
-
-To run the main types of tests locally:
-
-- Run package-internal tests with `nix-build --attr pkgs.PACKAGE.passthru.tests`
-- Run [NixOS tests](https://nixos.org/manual/nixos/unstable/#sec-nixos-tests) with `nix-build --attr nixosTest.NAME`, where `NAME` is the name of the test listed in `nixos/tests/all-tests.nix`
-- Run [global package tests](https://nixos.org/manual/nixpkgs/unstable/#sec-package-tests) with `nix-build --attr tests.PACKAGE`, where `PACKAGE` is the name of the test listed in `pkgs/test/default.nix`
-- See `lib/tests/NAME.nix` for instructions on running specific library tests
-
-## Rebasing between branches (i.e. from master to staging)
-
-From time to time, changes between branches must be rebased, for example, if the
-number of new rebuilds they would cause is too large for the target branch. When
-rebasing, care must be taken to include only the intended changes, otherwise
-many CODEOWNERS will be inadvertently requested for review. To achieve this,
-rebasing should not be performed directly on the target branch, but on the merge
-base between the current and target branch. As an additional precautionary measure,
-you should temporarily mark the PR as draft for the duration of the operation.
-This reduces the probability of mass-pinging people. (OfBorg might still
-request a couple of persons for reviews though.)
-
-In the following example, we assume that the current branch, called `feature`,
-is based on `master`, and we rebase it onto the merge base between
-`master` and `staging` so that the PR can eventually be retargeted to
-`staging` without causing a mess. The example uses `upstream` as the remote for `NixOS/nixpkgs.git`
-while `origin` is the remote you are pushing to.
-
-
-```console
-# Rebase your commits onto the common merge base
-git rebase --onto upstream/staging... upstream/master
-# Force push your changes
-git push origin feature --force-with-lease
-```
-
-The syntax `upstream/staging...` is equivalent to `upstream/staging...HEAD` and
-stands for the merge base between `upstream/staging` and `HEAD` (hence between
-`upstream/staging` and `upstream/master`).
-
-Then change the base branch in the GitHub PR using the *Edit* button in the upper
-right corner, and switch from `master` to `staging`. *After* the PR has been
-retargeted it might be necessary to do a final rebase onto the target branch, to
-resolve any outstanding merge conflicts.
-
-```console
-# Rebase onto target branch
-git rebase upstream/staging
-# Review and fixup possible conflicts
-git status
-# Force push your changes
-git push origin feature --force-with-lease
-```
-
-### Something went wrong and a lot of people were pinged
-
-It happens. Remember to be kind, especially to new contributors.
-There is no way back, so the pull request should be closed and locked
-(if possible). The changes should be re-submitted in a new PR, in which the people
-originally involved in the conversation need to manually be pinged again.
-No further discussion should happen on the original PR, as a lot of people
-are now subscribed to it.
-
-The following message (or a version thereof) might be left when closing to
-describe the situation, since closing and locking without any explanation
-is kind of rude:
-
-```markdown
-It looks like you accidentally mass-pinged a bunch of people, which are now subscribed
-and getting notifications for everything in this pull request. Unfortunately, they
-cannot be automatically unsubscribed from the issue (removing review request does not
-unsubscribe), therefore development cannot continue in this pull request anymore.
-
-Please open a new pull request with your changes, link back to this one and ping the
-people actually involved in here over there.
-
-In order to avoid this in the future, there are instructions for how to properly
-rebase between branches in our [contribution guidelines](https://github.com/NixOS/nixpkgs/blob/master/CONTRIBUTING.md#rebasing-between-branches-ie-from-master-to-staging).
-Setting your pull request to draft prior to rebasing is strongly recommended.
-In draft status, you can preview the list of people that are about to be requested
-for review, which allows you to sidestep this issue.
-This is not a bulletproof method though, as OfBorg still does review requests even on draft PRs.
-```
-
-## Backporting changes
-
-Follow these steps to backport a change into a release branch in compliance with the [commit policy](https://nixos.org/nixpkgs/manual/#submitting-changes-stable-release-branches).
-
-You can add a label such as `backport release-23.05` to a PR, so that merging it will
-automatically create a backport (via [a GitHub Action](.github/workflows/backport.yml)).
-This also works for pull requests that have already been merged, and might take a couple of minutes to trigger.
-
-You can also create the backport manually:
-
-1. Take note of the commits in which the change was introduced into `master` branch.
-2. Check out the target _release branch_, e.g. `release-23.05`. Do not use a _channel branch_ like `nixos-23.05` or `nixpkgs-23.05-darwin`.
-3. Create a branch for your change, e.g. `git checkout -b backport`.
-4. When the reason to backport is not obvious from the original commit message, use `git cherry-pick -xe <original commit>` and add a reason. Otherwise use `git cherry-pick -x <original commit>`. That's fine for minor version updates that only include security and bug fixes, commits that fixes an otherwise broken package or similar. Please also ensure the commits exists on the master branch; in the case of squashed or rebased merges, the commit hash will change and the new commits can be found in the merge message at the bottom of the master pull request.
-5. Push to GitHub and open a backport pull request. Make sure to select the release branch (e.g. `release-23.05`) as the target branch of the pull request, and link to the pull request in which the original change was committed to `master`. The pull request title should be the commit title with the release version as prefix, e.g. `[23.05]`.
-6. When the backport pull request is merged and you have the necessary privileges you can also replace the label `9.needs: port to stable` with `8.has: port to stable` on the original pull request. This way maintainers can keep track of missing backports easier.
-
-## Criteria for Backporting changes
-
-Anything that does not cause user or downstream dependency regressions can be backported. This includes:
-- New Packages / Modules
-- Security / Patch updates
-- Version updates which include new functionality (but no breaking changes)
-- Services which require a client to be up-to-date regardless. (E.g. `spotify`, `steam`, or `discord`)
-- Security critical applications (E.g. `firefox`)

-# Other Project Repositories
-
-The sources of all official Nix-related projects are in the [NixOS
-organization on GitHub](https://github.com/NixOS/). Here are some of
-the main ones:
-
-* [Nix](https://github.com/NixOS/nix) - the purely functional package manager
-* [NixOps](https://github.com/NixOS/nixops) - the tool to remotely deploy NixOS machines
-* [nixos-hardware](https://github.com/NixOS/nixos-hardware) - NixOS profiles to optimize settings for different hardware

-
-# Continuous Integration and Distribution
-
-Nixpkgs and NixOS are built and tested by our continuous integration
-system, [Hydra](https://hydra.nixos.org/).
-
-* [Continuous package builds for unstable/master](https://hydra.nixos.org/jobset/nixos/trunk-combined)
-* [Continuous package builds for the NixOS 23.05 release](https://hydra.nixos.org/jobset/nixos/release-23.05)
-* [Tests for unstable/master](https://hydra.nixos.org/job/nixos/trunk-combined/tested#tabs-constituents)
-* [Tests for the NixOS 23.05 release](https://hydra.nixos.org/job/nixos/release-23.05/tested#tabs-constituents)
-
-Artifacts successfully built with Hydra are published to cache at
-https://cache.nixos.org/. When successful build and test criteria are
-met, the Nixpkgs expressions are distributed via [Nix
-channels](https://nixos.org/manual/nix/stable/package-management/channels.html).
-
-# Contributing
-
-Nixpkgs is among the most active projects on GitHub. While thousands
-of open issues and pull requests might seem a lot at first, it helps
-consider it in the context of the scope of the project. Nixpkgs
-describes how to build tens of thousands of pieces of software and implements a
-Linux distribution. The [GitHub Insights](https://github.com/NixOS/nixpkgs/pulse)
-page gives a sense of the project activity.
-
-Community contributions are always welcome through GitHub Issues and
-Pull Requests. When pull requests are made, our tooling automation bot,
-[OfBorg](https://github.com/NixOS/ofborg) will perform various checks
-to help ensure expression quality.
-
-The *Nixpkgs maintainers* are people who have assigned themselves to
-maintain specific individual packages. We encourage people who care
-about a package to assign themselves as a maintainer. When a pull
-request is made against a package, OfBorg will notify the appropriate
-maintainer(s). The *Nixpkgs committers* are people who have been given
-permission to merge.
-
-Most contributions are based on and merged into these branches:
-
-* `master` is the main branch where all small contributions go
-* `staging` is branched from master, changes that have a big impact on
-  Hydra builds go to this branch
-* `staging-next` is branched from staging and only fixes to stabilize
-  and security fixes with a big impact on Hydra builds should be
-  contributed to this branch. This branch is merged into master when
-  deemed of sufficiently high quality
-
-For more information about contributing to the project, please visit
-the [contributing page](https://github.com/NixOS/nixpkgs/blob/master/CONTRIBUTING.md).
-
-# Donations
-
-The infrastructure for NixOS and related projects is maintained by a
-nonprofit organization, the [NixOS
-Foundation](https://nixos.org/nixos/foundation.html). To ensure the
-continuity and expansion of the NixOS infrastructure, we are looking
-for donations to our organization.
-
-You can donate to the NixOS foundation through [SEPA bank
-transfers](https://nixos.org/donate.html) or by using Open Collective:

-# Fetchers {#chap-pkgs-fetchers}
-
-Building software with Nix often requires downloading source code and other files from the internet.
-`nixpkgs` provides *fetchers* for different protocols and services. Fetchers are functions that simplify downloading files.
-
-## Caveats {#chap-pkgs-fetchers-caveats}
-
-Fetchers create [fixed output derivations](https://nixos.org/manual/nix/stable/#fixed-output-drvs) from downloaded files.
-Nix can reuse the downloaded files via the hash of the resulting derivation.
-
-The fact that the hash belongs to the Nix derivation output and not the file itself can lead to confusion.
-For example, consider the following fetcher:
-
-```nix
-fetchurl {
-  url = "http://www.example.org/hello-1.0.tar.gz";
-  hash = "sha256-lTeyxzJNQeMdu1IVdovNMtgn77jRIhSybLdMbTkf2Ww=";
-};
-```
-
-A common mistake is to update a fetcher’s URL, or a version parameter, without updating the hash.
-
-```nix
-fetchurl {
-  url = "http://www.example.org/hello-1.1.tar.gz";
-  hash = "sha256-lTeyxzJNQeMdu1IVdovNMtgn77jRIhSybLdMbTkf2Ww=";
-};
-```
-
-**This will reuse the old contents**.
-Remember to invalidate the hash argument, in this case by setting the `hash` attribute to an empty string.
-
-```nix
-fetchurl {
-  url = "http://www.example.org/hello-1.1.tar.gz";
-  hash = "";
-};
-```
-
-Use the resulting error message to determine the correct hash.
-
-```
-error: hash mismatch in fixed-output derivation '/path/to/my.drv':
-         specified: sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=
-            got:    sha256-lTeyxzJNQeMdu1IVdovNMtgn77jRIhSybLdMbTkf2Ww=
-```
-
-A similar problem arises while testing changes to a fetcher's implementation. If the output of the derivation already exists in the Nix store, test failures can go undetected. The [`invalidateFetcherByDrvHash`](#tester-invalidateFetcherByDrvHash) function helps prevent reusing cached derivations.
-
-## `fetchurl` and `fetchzip` {#fetchurl}
-
-Two basic fetchers are `fetchurl` and `fetchzip`. Both of these have two required arguments, a URL and a hash. The hash is typically `hash`, although many more hash algorithms are supported. Nixpkgs contributors are currently recommended to use `hash`. This hash will be used by Nix to identify your source. A typical usage of `fetchurl` is provided below.
-
-```nix
-{ stdenv, fetchurl }:
-
-stdenv.mkDerivation {
-  name = "hello";
-  src = fetchurl {
-    url = "http://www.example.org/hello.tar.gz";
-    hash = "sha256-BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB=";
-  };
-}
-```
-
-The main difference between `fetchurl` and `fetchzip` is in how they store the contents. `fetchurl` will store the unaltered contents of the URL within the Nix store. `fetchzip` on the other hand, will decompress the archive for you, making files and directories directly accessible in the future. `fetchzip` can only be used with archives. Despite the name, `fetchzip` is not limited to .zip files and can also be used with any tarball.
-
-## `fetchpatch` {#fetchpatch}
-
-`fetchpatch` works very similarly to `fetchurl` with the same arguments expected. It expects patch files as a source and performs normalization on them before computing the checksum. For example, it will remove comments or other unstable parts that are sometimes added by version control systems and can change over time.
-
-- `relative`: Similar to using `git-diff`'s `--relative` flag, only keep changes inside the specified directory, making paths relative to it.
-- `stripLen`: Remove the first `stripLen` components of pathnames in the patch.
-- `decode`: Pipe the downloaded data through this command before processing it as a patch.
-- `extraPrefix`: Prefix pathnames by this string.
-- `excludes`: Exclude files matching these patterns (applies after the above arguments).
-- `includes`: Include only files matching these patterns (applies after the above arguments).
-- `revert`: Revert the patch.
-
-Note that because the checksum is computed after applying these effects, using or modifying these arguments will have no effect unless the `hash` argument is changed as well.
-
-
-Most other fetchers return a directory rather than a single file.
-
-## `fetchsvn` {#fetchsvn}
-
-Used with Subversion. Expects `url` to a Subversion directory, `rev`, and `hash`.
-
-## `fetchgit` {#fetchgit}
-
-Used with Git. Expects `url` to a Git repo, `rev`, and `hash`. `rev` in this case can be full the git commit id (SHA1 hash) or a tag name like `refs/tags/v1.0`.
-
-Additionally, the following optional arguments can be given: `fetchSubmodules = true` makes `fetchgit` also fetch the submodules of a repository. If `deepClone` is set to true, the entire repository is cloned as opposing to just creating a shallow clone. `deepClone = true` also implies `leaveDotGit = true` which means that the `.git` directory of the clone won't be removed after checkout.
-
-If only parts of the repository are needed, `sparseCheckout` can be used. This will prevent git from fetching unnecessary blobs from server, see [git sparse-checkout](https://git-scm.com/docs/git-sparse-checkout) for more information:
-
-```nix
-{ stdenv, fetchgit }:
-
-stdenv.mkDerivation {
-  name = "hello";
-  src = fetchgit {
-    url = "https://...";
-    sparseCheckout = [
-      "directory/to/be/included"
-      "another/directory"
-    ];
-    hash = "sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=";
-  };
-}
-```
-
-## `fetchfossil` {#fetchfossil}
-
-Used with Fossil. Expects `url` to a Fossil archive, `rev`, and `hash`.
-
-## `fetchcvs` {#fetchcvs}
-
-Used with CVS. Expects `cvsRoot`, `tag`, and `hash`.
-
-## `fetchhg` {#fetchhg}
-
-Used with Mercurial. Expects `url`, `rev`, and `hash`.
-
-A number of fetcher functions wrap part of `fetchurl` and `fetchzip`. They are mainly convenience functions intended for commonly used destinations of source code in Nixpkgs. These wrapper fetchers are listed below.
-
-## `fetchFromGitea` {#fetchfromgitea}
-
-`fetchFromGitea` expects five arguments. `domain` is the gitea server name. `owner` is a string corresponding to the Gitea user or organization that controls this repository. `repo` corresponds to the name of the software repository. These are located at the top of every Gitea HTML page as `owner`/`repo`. `rev` corresponds to the Git commit hash or tag (e.g `v1.0`) that will be downloaded from Git. Finally, `hash` corresponds to the hash of the extracted directory. Again, other hash algorithms are also available but `hash` is currently preferred.
-
-## `fetchFromGitHub` {#fetchfromgithub}
-
-`fetchFromGitHub` expects four arguments. `owner` is a string corresponding to the GitHub user or organization that controls this repository. `repo` corresponds to the name of the software repository. These are located at the top of every GitHub HTML page as `owner`/`repo`. `rev` corresponds to the Git commit hash or tag (e.g `v1.0`) that will be downloaded from Git. Finally, `hash` corresponds to the hash of the extracted directory. Again, other hash algorithms are also available, but `hash` is currently preferred.
-
-To use a different GitHub instance, use `githubBase` (defaults to `"github.com"`).
-
-`fetchFromGitHub` uses `fetchzip` to download the source archive generated by GitHub for the specified revision. If `leaveDotGit`, `deepClone` or `fetchSubmodules` are set to `true`, `fetchFromGitHub` will use `fetchgit` instead. Refer to its section for documentation of these options.
-
-## `fetchFromGitLab` {#fetchfromgitlab}
-
-This is used with GitLab repositories. It behaves similarly to `fetchFromGitHub`, and expects `owner`, `repo`, `rev`, and `hash`.
-
-To use a specific GitLab instance, use `domain` (defaults to `"gitlab.com"`).
-
-
-## `fetchFromGitiles` {#fetchfromgitiles}
-
-This is used with Gitiles repositories. The arguments expected are similar to `fetchgit`.
-
-## `fetchFromBitbucket` {#fetchfrombitbucket}
-
-This is used with BitBucket repositories. The arguments expected are very similar to `fetchFromGitHub` above.
-
-## `fetchFromSavannah` {#fetchfromsavannah}
-
-This is used with Savannah repositories. The arguments expected are very similar to `fetchFromGitHub` above.
-
-## `fetchFromRepoOrCz` {#fetchfromrepoorcz}
-
-This is used with repo.or.cz repositories. The arguments expected are very similar to `fetchFromGitHub` above.
-
-## `fetchFromSourcehut` {#fetchfromsourcehut}
-
-This is used with sourcehut repositories. Similar to `fetchFromGitHub` above,
-it expects `owner`, `repo`, `rev` and `hash`, but don't forget the tilde (~)
-in front of the username! Expected arguments also include `vc` ("git" (default)
-or "hg"), `domain` and `fetchSubmodules`.
-
-If `fetchSubmodules` is `true`, `fetchFromSourcehut` uses `fetchgit`
-or `fetchhg` with `fetchSubmodules` or `fetchSubrepos` set to `true`,
-respectively. Otherwise, the fetcher uses `fetchzip`.
-
-## `requireFile` {#requirefile}
-
-`requireFile` allows requesting files that cannot be fetched automatically, but whose content is known.
-This is a useful last-resort workaround for license restrictions that prohibit redistribution, or for downloads that are only accessible after authenticating interactively in a browser.
-If the requested file is present in the Nix store, the resulting derivation will not be built, because its expected output is already available.
-Otherwise, the builder will run, but fail with a message explaining to the user how to provide the file. The following code, for example:
-
-```
-requireFile {
-  name = "jdk-${version}_linux-x64_bin.tar.gz";
-  url = "https://www.oracle.com/java/technologies/javase-jdk11-downloads.html";
-  sha256 = "94bd34f85ee38d3ef59e5289ec7450b9443b924c55625661fffe66b03f2c8de2";
-}
-```
-results in this error message:
-```
-***
-Unfortunately, we cannot download file jdk-11.0.10_linux-x64_bin.tar.gz automatically.
-Please go to https://www.oracle.com/java/technologies/javase-jdk11-downloads.html to download it yourself, and add it to the Nix store
-using either
-  nix-store --add-fixed sha256 jdk-11.0.10_linux-x64_bin.tar.gz
-or
-  nix-prefetch-url --type sha256 file:///path/to/jdk-11.0.10_linux-x64_bin.tar.gz

-
-- `name` specifies the name of the resulting image.
-- `src` specifies the AppImage file to extract.
-- `extraPkgs` allows you to pass a function to include additional packages inside the FHS environment your AppImage is going to run in. There are a few ways to learn which dependencies an application needs:
-  - Looking through the extracted AppImage files, reading its scripts and running `patchelf` and `ldd` on its executables. This can also be done in `appimage-run`, by setting `APPIMAGE_DEBUG_EXEC=bash`.
-  - Running `strace -vfefile` on the wrapped executable, looking for libraries that can't be found.

-# pkgs.mkBinaryCache {#sec-pkgs-binary-cache}
-
-`pkgs.mkBinaryCache` is a function for creating Nix flat-file binary caches. Such a cache exists as a directory on disk, and can be used as a Nix substituter by passing `--substituter file:///path/to/cache` to Nix commands.
-
-Nix packages are most commonly shared between machines using [HTTP, SSH, or S3](https://nixos.org/manual/nix/stable/package-management/sharing-packages.html), but a flat-file binary cache can still be useful in some situations. For example, you can copy it directly to another machine, or make it available on a network file system. It can also be a convenient way to make some Nix packages available inside a container via bind-mounting.
-
-Note that this function is meant for advanced use-cases. The more idiomatic way to work with flat-file binary caches is via the [nix-copy-closure](https://nixos.org/manual/nix/stable/command-ref/nix-copy-closure.html) command. You may also want to consider [dockerTools](#sec-pkgs-dockerTools) for your containerization needs.
-
-## Example {#sec-pkgs-binary-cache-example}
-
-The following derivation will construct a flat-file binary cache containing the closure of `hello`.
-
-```nix
-mkBinaryCache {
-  rootPaths = [hello];
-}
-```
-
-- `rootPaths` specifies a list of root derivations. The transitive closure of these derivations' outputs will be copied into the cache.
-
-Here's an example of building and using the cache.
-
-Build the cache on one machine, `host1`:
-
-```shellSession
-nix-build -E 'with import <nixpkgs> {}; mkBinaryCache { rootPaths = [hello]; }'
-```
-
-```shellSession
-/nix/store/cc0562q828rnjqjyfj23d5q162gb424g-binary-cache
-```
-
-Copy the resulting directory to the other machine, `host2`:
-
-```shellSession
-scp result host2:/tmp/hello-cache
-```
-
-Substitute the derivation using the flat-file binary cache on the other machine, `host2`:
-```shellSession
-nix-build -A hello '<nixpkgs>' \
-  --option require-sigs false \
-  --option trusted-substituters file:///tmp/hello-cache \
-  --option substituters file:///tmp/hello-cache

-# pkgs.dockerTools {#sec-pkgs-dockerTools}
-
-`pkgs.dockerTools` is a set of functions for creating and manipulating Docker images according to the [Docker Image Specification v1.2.0](https://github.com/moby/moby/blob/master/image/spec/v1.2.md#docker-image-specification-v120). Docker itself is not used to perform any of the operations done by these functions.
-
-## buildImage {#ssec-pkgs-dockerTools-buildImage}
-
-This function is analogous to the `docker build` command, in that it can be used to build a Docker-compatible repository tarball containing a single image with one or multiple layers. As such, the result is suitable for being loaded in Docker with `docker load`.
-
-The parameters of `buildImage` with relative example values are described below:
-
-[]{#ex-dockerTools-buildImage}
-[]{#ex-dockerTools-buildImage-runAsRoot}
-
-```nix
-buildImage {
-  name = "redis";
-  tag = "latest";
-
-  fromImage = someBaseImage;
-  fromImageName = null;
-  fromImageTag = "latest";
-
-  copyToRoot = pkgs.buildEnv {
-    name = "image-root";
-    paths = [ pkgs.redis ];
-    pathsToLink = [ "/bin" ];
-  };
-
-  runAsRoot = ''
-    #!${pkgs.runtimeShell}
-    mkdir -p /data
-  '';
-
-  config = {
-    Cmd = [ "/bin/redis-server" ];
-    WorkingDir = "/data";
-    Volumes = { "/data" = { }; };
-  };
-
-  diskSize = 1024;
-  buildVMMemorySize = 512;
-}
-```
-
-The above example will build a Docker image `redis/latest` from the given base image. Loading and running this image in Docker results in `redis-server` being started automatically.
-
-- `name` specifies the name of the resulting image. This is the only required argument for `buildImage`.
-
-- `tag` specifies the tag of the resulting image. By default it's `null`, which indicates that the nix output hash will be used as tag.
-
-- `fromImage` is the repository tarball containing the base image. It must be a valid Docker image, such as exported by `docker save`. By default it's `null`, which can be seen as equivalent to `FROM scratch` of a `Dockerfile`.
-
-- `fromImageName` can be used to further specify the base image within the repository, in case it contains multiple images. By default it's `null`, in which case `buildImage` will peek the first image available in the repository.
-
-- `fromImageTag` can be used to further specify the tag of the base image within the repository, in case an image contains multiple tags. By default it's `null`, in which case `buildImage` will peek the first tag available for the base image.
-
-- `copyToRoot` is a derivation that will be copied in the new layer of the resulting image. This can be similarly seen as `ADD contents/ /` in a `Dockerfile`. By default it's `null`.
-
-- `runAsRoot` is a bash script that will run as root in an environment that overlays the existing layers of the base image with the new resulting layer, including the previously copied `contents` derivation. This can be similarly seen as `RUN ...` in a `Dockerfile`.
-
-> **_NOTE:_** Using this parameter requires the `kvm` device to be available.
-
-- `config` is used to specify the configuration of the containers that will be started off the built image in Docker. The available options are listed in the [Docker Image Specification v1.2.0](https://github.com/moby/moby/blob/master/image/spec/v1.2.md#image-json-field-descriptions).
-
-- `architecture` is _optional_ and used to specify the image architecture, this is useful for multi-architecture builds that don't need cross compiling. If not specified it will default to `hostPlatform`.
-
-- `diskSize` is used to specify the disk size of the VM used to build the image in megabytes. By default it's 1024 MiB.
-
-- `buildVMMemorySize` is used to specify the memory size of the VM to build the image in megabytes. By default it's 512 MiB.
-
-After the new layer has been created, its closure (to which `contents`, `config` and `runAsRoot` contribute) will be copied in the layer itself. Only new dependencies that are not already in the existing layers will be copied.
-
-At the end of the process, only one new single layer will be produced and added to the resulting image.
-
-The resulting repository will only list the single image `image/tag`. In the case of [the `buildImage` example](#ex-dockerTools-buildImage), it would be `redis/latest`.
-
-It is possible to inspect the arguments with which an image was built using its `buildArgs` attribute.
-
-> **_NOTE:_** If you see errors similar to `getProtocolByName: does not exist (no such protocol name: tcp)` you may need to add `pkgs.iana-etc` to `contents`.
-
-> **_NOTE:_** If you see errors similar to `Error_Protocol ("certificate has unknown CA",True,UnknownCa)` you may need to add `pkgs.cacert` to `contents`.
-
-By default `buildImage` will use a static date of one second past the UNIX Epoch. This allows `buildImage` to produce binary reproducible images. When listing images with `docker images`, the newly created images will be listed like this:
-
-```ShellSession
-$ docker images
-REPOSITORY   TAG      IMAGE ID       CREATED        SIZE
-hello        latest   08c791c7846e   48 years ago   25.2MB
-```
-
-You can break binary reproducibility but have a sorted, meaningful `CREATED` column by setting `created` to `now`.
-
-```nix
-pkgs.dockerTools.buildImage {
-  name = "hello";
-  tag = "latest";
-  created = "now";
-  copyToRoot = pkgs.buildEnv {
-    name = "image-root";
-    paths = [ pkgs.hello ];
-    pathsToLink = [ "/bin" ];
-  };
-
-  config.Cmd = [ "/bin/hello" ];
-}
-```
-
-Now the Docker CLI will display a reasonable date and sort the images as expected:

-
-However, the produced images will not be binary reproducible.
-
-## buildLayeredImage {#ssec-pkgs-dockerTools-buildLayeredImage}
-
-Create a Docker image with many of the store paths being on their own layer to improve sharing between images. The image is realized into the Nix store as a gzipped tarball. Depending on the intended usage, many users might prefer to use `streamLayeredImage` instead, which this function uses internally.
-
-`name`
-
-: The name of the resulting image.
-
-`tag` _optional_
-
-: Tag of the generated image.
-
-    *Default:* the output path's hash
-
-`fromImage` _optional_
-
-: The repository tarball containing the base image. It must be a valid Docker image, such as one exported by `docker save`.
-
-    *Default:* `null`, which can be seen as equivalent to `FROM scratch` of a `Dockerfile`.
-
-`contents` _optional_
-
-: Top-level paths in the container. Either a single derivation, or a list of derivations.
-
-    *Default:* `[]`
-
-`config` _optional_
-
-`architecture` is _optional_ and used to specify the image architecture, this is useful for multi-architecture builds that don't need cross compiling. If not specified it will default to `hostPlatform`.
-
-: Run-time configuration of the container. A full list of the options available is in the [Docker Image Specification v1.2.0](https://github.com/moby/moby/blob/master/image/spec/v1.2.md#image-json-field-descriptions).
-
-    *Default:* `{}`
-
-`created` _optional_
-
-: Date and time the layers were created. Follows the same `now` exception supported by `buildImage`.
-
-    *Default:* `1970-01-01T00:00:01Z`
-
-`maxLayers` _optional_
-
-: Maximum number of layers to create.
-
-    *Default:* `100`
-
-    *Maximum:* `125`
-
-`extraCommands` _optional_
-
-: Shell commands to run while building the final layer, without access to most of the layer contents. Changes to this layer are "on top" of all the other layers, so can create additional directories and files.
-
-`fakeRootCommands` _optional_
-
-: Shell commands to run while creating the archive for the final layer in a fakeroot environment. Unlike `extraCommands`, you can run `chown` to change the owners of the files in the archive, changing fakeroot's state instead of the real filesystem. The latter would require privileges that the build user does not have. Static binaries do not interact with the fakeroot environment. By default all files in the archive will be owned by root.
-
-`enableFakechroot` _optional_
-
-: Whether to run in `fakeRootCommands` in `fakechroot`, making programs behave as though `/` is the root of the image being created, while files in the Nix store are available as usual. This allows scripts that perform installation in `/` to work as expected. Considering that `fakechroot` is implemented via the same mechanism as `fakeroot`, the same caveats apply.
-
-    *Default:* `false`
-
-### Behavior of `contents` in the final image {#dockerTools-buildLayeredImage-arg-contents}
-
-Each path directly listed in `contents` will have a symlink in the root of the image.
-
-For example:
-
-```nix
-pkgs.dockerTools.buildLayeredImage {
-  name = "hello";
-  contents = [ pkgs.hello ];
-}
-```
-
-will create symlinks for all the paths in the `hello` package:
-
-```ShellSession
-/bin/hello -> /nix/store/h1zb1padqbbb7jicsvkmrym3r6snphxg-hello-2.10/bin/hello
-/share/info/hello.info -> /nix/store/h1zb1padqbbb7jicsvkmrym3r6snphxg-hello-2.10/share/info/hello.info
-/share/locale/bg/LC_MESSAGES/hello.mo -> /nix/store/h1zb1padqbbb7jicsvkmrym3r6snphxg-hello-2.10/share/locale/bg/LC_MESSAGES/hello.mo
-```
-
-### Automatic inclusion of `config` references {#dockerTools-buildLayeredImage-arg-config}
-
-The closure of `config` is automatically included in the closure of the final image.
-
-This allows you to make very simple Docker images with very little code. This container will start up and run `hello`:
-
-```nix
-pkgs.dockerTools.buildLayeredImage {
-  name = "hello";
-  config.Cmd = [ "${pkgs.hello}/bin/hello" ];
-}
-```
-
-### Adjusting `maxLayers` {#dockerTools-buildLayeredImage-arg-maxLayers}
-
-Increasing the `maxLayers` increases the number of layers which have a chance to be shared between different images.
-
-Modern Docker installations support up to 128 layers, but older versions support as few as 42.
-
-If the produced image will not be extended by other Docker builds, it is safe to set `maxLayers` to `128`. However, it will be impossible to extend the image further.
-
-The first (`maxLayers-2`) most "popular" paths will have their own individual layers, then layer \#`maxLayers-1` will contain all the remaining "unpopular" paths, and finally layer \#`maxLayers` will contain the Image configuration.
-
-Docker's Layers are not inherently ordered, they are content-addressable and are not explicitly layered until they are composed in to an Image.
-
-## streamLayeredImage {#ssec-pkgs-dockerTools-streamLayeredImage}
-
-Builds a script which, when run, will stream an uncompressed tarball of a Docker image to stdout. The arguments to this function are as for `buildLayeredImage`. This method of constructing an image does not realize the image into the Nix store, so it saves on IO and disk/cache space, particularly with large images.
-
-The image produced by running the output script can be piped directly into `docker load`, to load it into the local docker daemon:
-
-```ShellSession
-$(nix-build) | docker load
-```
-
-Alternatively, the image be piped via `gzip` into `skopeo`, e.g., to copy it into a registry:
-
-```ShellSession
-$(nix-build) | gzip --fast | skopeo copy docker-archive:/dev/stdin docker://some_docker_registry/myimage:tag
-```
-
-## pullImage {#ssec-pkgs-dockerTools-fetchFromRegistry}
-
-This function is analogous to the `docker pull` command, in that it can be used to pull a Docker image from a Docker registry. By default [Docker Hub](https://hub.docker.com/) is used to pull images.
-
-Its parameters are described in the example below:
-
-```nix
-pullImage {
-  imageName = "nixos/nix";
-  imageDigest =
-    "sha256:473a2b527958665554806aea24d0131bacec46d23af09fef4598eeab331850fa";
-  finalImageName = "nix";
-  finalImageTag = "2.11.1";
-  sha256 = "sha256-qvhj+Hlmviz+KEBVmsyPIzTB3QlVAFzwAY1zDPIBGxc=";
-  os = "linux";
-  arch = "x86_64";
-}
-```
-
-- `imageName` specifies the name of the image to be downloaded, which can also include the registry namespace (e.g. `nixos`). This argument is required.
-
-- `imageDigest` specifies the digest of the image to be downloaded. This argument is required.
-
-- `finalImageName`, if specified, this is the name of the image to be created. Note it is never used to fetch the image since we prefer to rely on the immutable digest ID. By default it's equal to `imageName`.
-
-- `finalImageTag`, if specified, this is the tag of the image to be created. Note it is never used to fetch the image since we prefer to rely on the immutable digest ID. By default it's `latest`.
-
-- `sha256` is the checksum of the whole fetched image. This argument is required.
-
-- `os`, if specified, is the operating system of the fetched image. By default it's `linux`.
-
-- `arch`, if specified, is the cpu architecture of the fetched image. By default it's `x86_64`.
-
-`nix-prefetch-docker` command can be used to get required image parameters:
-
-```ShellSession
-$ nix run nixpkgs.nix-prefetch-docker -c nix-prefetch-docker --image-name mysql --image-tag 5
-```
-
-Since a given `imageName` may transparently refer to a manifest list of images which support multiple architectures and/or operating systems, you can supply the `--os` and `--arch` arguments to specify exactly which image you want. By default it will match the OS and architecture of the host the command is run on.
-
-```ShellSession
-$ nix-prefetch-docker --image-name mysql --image-tag 5 --arch x86_64 --os linux
-```
-
-Desired image name and tag can be set using `--final-image-name` and `--final-image-tag` arguments:
-
-```ShellSession
-$ nix-prefetch-docker --image-name mysql --image-tag 5 --final-image-name eu.gcr.io/my-project/mysql --final-image-tag prod
-```
-
-## exportImage {#ssec-pkgs-dockerTools-exportImage}
-
-This function is analogous to the `docker export` command, in that it can be used to flatten a Docker image that contains multiple layers. It is in fact the result of the merge of all the layers of the image. As such, the result is suitable for being imported in Docker with `docker import`.
-
-> **_NOTE:_** Using this function requires the `kvm` device to be available.
-
-The parameters of `exportImage` are the following:
-
-```nix
-exportImage {
-  fromImage = someLayeredImage;
-  fromImageName = null;
-  fromImageTag = null;
-
-  name = someLayeredImage.name;
-}
-```
-
-The parameters relative to the base image have the same synopsis as described in [buildImage](#ssec-pkgs-dockerTools-buildImage), except that `fromImage` is the only required argument in this case.
-
-The `name` argument is the name of the derivation output, which defaults to `fromImage.name`.
-
-## Environment Helpers {#ssec-pkgs-dockerTools-helpers}
-
-Some packages expect certain files to be available globally.
-When building an image from scratch (i.e. without `fromImage`), these files are missing.
-`pkgs.dockerTools` provides some helpers to set up an environment with the necessary files.
-You can include them in `copyToRoot` like this:
-
-```nix
-buildImage {
-  name = "environment-example";
-  copyToRoot = with pkgs.dockerTools; [
-    usrBinEnv
-    binSh
-    caCertificates
-    fakeNss
-  ];
-}
-```
-
-### usrBinEnv {#sssec-pkgs-dockerTools-helpers-usrBinEnv}
-
-This provides the `env` utility at `/usr/bin/env`.
-
-### binSh {#sssec-pkgs-dockerTools-helpers-binSh}
-
-This provides `bashInteractive` at `/bin/sh`.
-
-### caCertificates {#sssec-pkgs-dockerTools-helpers-caCertificates}
-
-This sets up `/etc/ssl/certs/ca-certificates.crt`.
-
-### fakeNss {#sssec-pkgs-dockerTools-helpers-fakeNss}
-
-Provides `/etc/passwd` and `/etc/group` that contain root and nobody.
-Useful when packaging binaries that insist on using nss to look up
-username/groups (like nginx).
-
-### shadowSetup {#ssec-pkgs-dockerTools-shadowSetup}
-
-This constant string is a helper for setting up the base files for managing users and groups, only if such files don't exist already. It is suitable for being used in a [`buildImage` `runAsRoot`](#ex-dockerTools-buildImage-runAsRoot) script for cases like in the example below:
-
-```nix
-buildImage {
-  name = "shadow-basic";
-
-  runAsRoot = ''
-    #!${pkgs.runtimeShell}
-    ${pkgs.dockerTools.shadowSetup}
-    groupadd -r redis
-    useradd -r -g redis redis
-    mkdir /data
-    chown redis:redis /data
-  '';
-}
-```
-
-Creating base files like `/etc/passwd` or `/etc/login.defs` is necessary for shadow-utils to manipulate users and groups.
-
-## fakeNss {#ssec-pkgs-dockerTools-fakeNss}
-
-If your primary goal is providing a basic skeleton for user lookups to work,
-and/or a lesser privileged user, adding `pkgs.fakeNss` to
-the container image root might be the better choice than a custom script
-running `useradd` and friends.
-
-It provides a `/etc/passwd` and `/etc/group`, containing `root` and `nobody`
-users and groups.
-
-It also provides a `/etc/nsswitch.conf`, configuring NSS host resolution to
-first check `/etc/hosts`, before checking DNS, as the default in the absence of
-a config file (`dns [!UNAVAIL=return] files`) is quite unexpected.
-
-You can pair it with `binSh`, which provides `bin/sh` as a symlink
-to `bashInteractive` (as `/bin/sh` is configured as a shell).
-
-```nix
-buildImage {
-  name = "shadow-basic";
-
-  copyToRoot = pkgs.buildEnv {
-    name = "image-root";
-    paths = [ binSh pkgs.fakeNss ];
-    pathsToLink = [ "/bin" "/etc" "/var" ];
-  };
-}
-```
-
-## buildNixShellImage {#ssec-pkgs-dockerTools-buildNixShellImage}
-
-Create a Docker image that sets up an environment similar to that of running `nix-shell` on a derivation.
-When run in Docker, this environment somewhat resembles the Nix sandbox typically used by `nix-build`, with a major difference being that access to the internet is allowed.
-It additionally also behaves like an interactive `nix-shell`, running things like `shellHook` and setting an interactive prompt.
-If the derivation is fully buildable (i.e. `nix-build` can be used on it), running `buildDerivation` inside such a Docker image will build the derivation, with all its outputs being available in the correct `/nix/store` paths, pointed to by the respective environment variables like `$out`, etc.
-
-::: {.warning}
-The behavior doesn't match `nix-shell` or `nix-build` exactly and this function is known not to work correctly for e.g. fixed-output derivations, content-addressed derivations, impure derivations and other special types of derivations.
-:::
-
-### Arguments {#ssec-pkgs-dockerTools-buildNixShellImage-arguments}
-
-`drv`
-
-: The derivation on which to base the Docker image.
-
-    Adding packages to the Docker image is possible by e.g. extending the list of `nativeBuildInputs` of this derivation like
-
-    ```nix
-    buildNixShellImage {
-      drv = someDrv.overrideAttrs (old: {
-        nativeBuildInputs = old.nativeBuildInputs or [] ++ [
-          somethingExtra
-        ];
-      });
-      # ...
-    }
-    ```
-
-    Similarly, you can extend the image initialization script by extending `shellHook`
-
-`name` _optional_
-
-: The name of the resulting image.
-
-    *Default:* `drv.name + "-env"`
-
-`tag` _optional_
-
-: Tag of the generated image.
-
-    *Default:* the resulting image derivation output path's hash
-
-`uid`/`gid` _optional_
-
-: The user/group ID to run the container as. This is like a `nixbld` build user.

-
-: The home directory of the user the container is running as
-
-    *Default:* `/build`
-
-`shell` _optional_
-
-: The path to the `bash` binary to use as the shell. This shell is started when running the image.
-
-    *Default:* `pkgs.bashInteractive + "/bin/bash"`
-
-`command` _optional_
-
-: Run this command in the environment of the derivation, in an interactive shell. See the `--command` option in the [`nix-shell` documentation](https://nixos.org/manual/nix/stable/command-ref/nix-shell.html?highlight=nix-shell#options).
-
-    *Default:* (none)
-
-`run` _optional_
-
-: Same as `command`, but runs the command in a non-interactive shell instead. See the `--run` option in the [`nix-shell` documentation](https://nixos.org/manual/nix/stable/command-ref/nix-shell.html?highlight=nix-shell#options).
-
-    *Default:* (none)
-
-### Example {#ssec-pkgs-dockerTools-buildNixShellImage-example}
-
-The following shows how to build the `pkgs.hello` package inside a Docker container built with `buildNixShellImage`.
-
-```nix
-with import <nixpkgs> {};
-dockerTools.buildNixShellImage {
-  drv = hello;

-# `<nixpkgs/nixos/lib/make-disk-image.nix>` {#sec-make-disk-image}
-
-`<nixpkgs/nixos/lib/make-disk-image.nix>` is a function to create _disk images_ in multiple formats: raw, QCOW2 (QEMU), QCOW2-Compressed (compressed version), VDI (VirtualBox), VPC (VirtualPC).
-
-This function can create images in two ways:
-
-- using `cptofs` without any virtual machine to create a Nix store disk image,
-- using a virtual machine to create a full NixOS installation.
-
-When testing early-boot or lifecycle parts of NixOS such as a bootloader or multiple generations, it is necessary to opt for a full NixOS system installation.
-Whereas for many web servers, applications, it is possible to work with a Nix store only disk image and is faster to build.
-
-NixOS tests also use this function when preparing the VM. The `cptofs` method is used when `virtualisation.useBootLoader` is false (the default). Otherwise the second method is used.
-
-## Features {#sec-make-disk-image-features}
-
-For reference, read the function signature source code for documentation on arguments: <https://github.com/NixOS/nixpkgs/blob/master/nixos/lib/make-disk-image.nix>.
-Features are separated in various sections depending on if you opt for a Nix-store only image or a full NixOS image.
-
-### Common {#sec-make-disk-image-features-common}
-
-- arbitrary NixOS configuration
-- automatic or bound disk size: `diskSize` parameter, `additionalSpace` can be set when `diskSize` is `auto` to add a constant of disk space
-- multiple partition table layouts: EFI, legacy, legacy + GPT, hybrid, none through `partitionTableType` parameter
-- OVMF or EFI firmwares and variables templates can be customized
-- root filesystem `fsType` can be customized to whatever `mkfs.${fsType}` exist during operations
-- root filesystem label can be customized, defaults to `nix-store` if it's a Nix store image, otherwise `nixpkgs/nixos`
-- arbitrary code can be executed after disk image was produced with `postVM`
-- the current nixpkgs can be realized as a channel in the disk image, which will change the hash of the image when the sources are updated
-- additional store paths can be provided through `additionalPaths`
-
-### Full NixOS image {#sec-make-disk-image-features-full-image}
-
-- arbitrary contents with permissions can be placed in the target filesystem using `contents`
-- a `/etc/nixpkgs/nixos/configuration.nix` can be provided through `configFile`
-- bootloaders are supported
-- EFI variables can be mutated during image production and the result is exposed in `$out`
-- boot partition size when partition table is `efi` or `hybrid`
-
-### On bit-to-bit reproducibility {#sec-make-disk-image-features-reproducibility}
-
-Images are **NOT** deterministic, please do not hesitate to try to fix this, source of determinisms are (not exhaustive) :
-
-- bootloader installation have timestamps
-- SQLite Nix store database contain registration times
-- `/etc/shadow` is in a non-deterministic order
-
-A `deterministic` flag is available for best efforts determinism.
-
-## Usage {#sec-make-disk-image-usage}
-
-To produce a Nix-store only image:
-```nix
-let
-  pkgs = import <nixpkgs> {};
-  lib = pkgs.lib;
-  make-disk-image = import <nixpkgs/nixos/lib/make-disk-image.nix>;
-in
-  make-disk-image {
-    inherit pkgs lib;
-    config = {};
-    additionalPaths = [ ];
-    format = "qcow2";
-    onlyNixStore = true;
-    partitionTableType = "none";
-    installBootLoader = false;
-    touchEFIVars = false;
-    diskSize = "auto";
-    additionalSpace = "0M"; # Defaults to 512M.
-    copyChannel = false;
-  }
-```
-
-Some arguments can be left out, they are shown explicitly for the sake of the example.
-
-Building this derivation will provide a QCOW2 disk image containing only the Nix store and its registration information.
-
-To produce a NixOS installation image disk with UEFI and bootloader installed:
-```nix
-let
-  pkgs = import <nixpkgs> {};
-  lib = pkgs.lib;
-  make-disk-image = import <nixpkgs/nixos/lib/make-disk-image.nix>;
-  evalConfig = import <nixpkgs/nixos/lib/eval-config.nix>;
-in
-  make-disk-image {
-    inherit pkgs lib;
-    config = evalConfig {
-      modules = [
-        {
-          fileSystems."/" = { device = "/dev/vda"; fsType = "ext4"; autoFormat = true; };
-          boot.grub.device = "/dev/vda";
-        }
-      ];
-    };
-    format = "qcow2";
-    onlyNixStore = false;
-    partitionTableType = "legacy+gpt";
-    installBootLoader = true;
-    touchEFIVars = true;
-    diskSize = "auto";
-    additionalSpace = "0M"; # Defaults to 512M.
-    copyChannel = false;
-    memSize = 2048; # Qemu VM memory size in megabytes. Defaults to 1024M.

-# pkgs.portableService {#sec-pkgs-portableService}
-
-`pkgs.portableService` is a function to create _portable service images_,
-as read-only, immutable, `squashfs` archives.
-
-systemd supports a concept of [Portable Services](https://systemd.io/PORTABLE_SERVICES/).
-Portable Services are a delivery method for system services that uses two specific features of container management:
-
-* Applications are bundled. I.e. multiple services, their binaries and
-  all their dependencies are packaged in an image, and are run directly from it.
-* Stricter default security policies, i.e. sandboxing of applications.
-
-This allows using Nix to build images which can be run on many recent Linux distributions.
-
-The primary tool for interacting with Portable Services is `portablectl`,
-and they are managed by the `systemd-portabled` system service.
-
-::: {.note}
-Portable services are supported starting with systemd 239 (released on 2018-06-22).

-[]{#ex-pkgs-portableService}
-
-```nix
-pkgs.portableService {
-  pname = "demo";
-  version = "1.0";
-  units = [ demo-service demo-socket ];
-}
-```
-
-The above example will build an squashfs archive image in `result/$pname_$version.raw`. The image will contain the
-file system structure as required by the portable service specification, and a subset of the Nix store with all the
-dependencies of the two derivations in the `units` list.
-`units` must be a list of derivations, and their names must be prefixed with the service name (`"demo"` in this case).
-Otherwise `systemd-portabled` will ignore them.
-
-::: {.note}
-The `.raw` file extension of the image is required by the portable services specification.
-:::
-
-Some other options available are:
-- `description`, `homepage`
-
-  Are added to the `/etc/os-release` in the image and are shown by the portable services tooling.
-  Default to empty values, not added to os-release.
-- `symlinks`
-
-  A list of attribute sets {object, symlink}. Symlinks will be created  in the root filesystem of the image to
-  objects in the Nix store. Defaults to an empty list.
-- `contents`
-
-  A list of additional derivations to be included in the image Nix store, as-is. Defaults to an empty list.
-- `squashfsTools`
-
-  Defaults to `pkgs.squashfsTools`, allows you to override the package that provides `mksquashfs`.
-- `squash-compression`, `squash-block-size`
-
-  Options to `mksquashfs`. Default to `"xz -Xdict-size 100%"` and `"1M"` respectively.
-
-A typical usage of `symlinks` would be:
-```nix
-  symlinks = [
-    { object = "${pkgs.cacert}/etc/ssl"; symlink = "/etc/ssl"; }
-    { object = "${pkgs.bash}/bin/bash"; symlink = "/bin/sh"; }
-    { object = "${pkgs.php}/bin/php"; symlink = "/usr/bin/php"; }
-  ];
-```
-to create these symlinks for legacy applications that assume them existing globally.
-
-Once the image is created, and deployed on a host in `/var/lib/portables/`, you can attach the image and run the service. As root run:
-```console
-portablectl attach demo_1.0.raw
-systemctl enable --now demo.socket
-systemctl enable --now demo.service
-```
-::: {.note}
-See the [man page](https://www.freedesktop.org/software/systemd/man/portablectl.html) of `portablectl` for more info on its usage.

-# pkgs.snapTools {#sec-pkgs-snapTools}
-
-`pkgs.snapTools` is a set of functions for creating Snapcraft images. Snap and Snapcraft is not used to perform these operations.
-
-## The makeSnap Function {#ssec-pkgs-snapTools-makeSnap-signature}
-
-`makeSnap` takes a single named argument, `meta`. This argument mirrors [the upstream `snap.yaml` format](https://docs.snapcraft.io/snap-format) exactly.
-
-The `base` should not be specified, as `makeSnap` will force set it.
-
-Currently, `makeSnap` does not support creating GUI stubs.
-
-## Build a Hello World Snap {#ssec-pkgs-snapTools-build-a-snap-hello}

-## How to install Cataclysm DDA {#how-to-install-cataclysm-dda}
-
-To install the latest stable release of Cataclysm DDA to your profile, execute
-`nix-env -f "<nixpkgs>" -iA cataclysm-dda`. For the curses build (build
-without tiles), install `cataclysmDDA.stable.curses`. Note: `cataclysm-dda` is
-an alias to `cataclysmDDA.stable.tiles`.
-
-If you like access to a development build of your favorite git revision,
-override `cataclysm-dda-git` (or `cataclysmDDA.git.curses` if you like curses
-build):
-
-```nix
-cataclysm-dda-git.override {
-  version = "YYYY-MM-DD";
-  rev = "YOUR_FAVORITE_REVISION";
-  sha256 = "CHECKSUM_OF_THE_REVISION";
-}
-```
-
-The sha256 checksum can be obtained by
-
-```sh
-nix-prefetch-url --unpack "https://github.com/CleverRaven/Cataclysm-DDA/archive/${YOUR_FAVORITE_REVISION}.tar.gz"
-```
-
-The default configuration directory is `~/.cataclysm-dda`. If you prefer

-After applying `overrideAttrs`, you need to fix `passthru.pkgs` and
-`passthru.withMods` attributes either manually or by using `attachPkgs`:
-
-```nix

-  # You enabled parallel building.
-  myCDDA = cataclysm-dda-git.overrideAttrs (_: {
-    enableParallelBuilding = true;

In order to work around this issue, the package provides a simple mechanism to add custom certificates without rebuilding the entire package using `symlinkJoin`:

-
-The Nix expressions related to the Eclipse platform and IDE are in [`pkgs/applications/editors/eclipse`](https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/editors/eclipse).
-
-Nixpkgs provides a number of packages that will install Eclipse in its various forms. These range from the bare-bones Eclipse Platform to the more fully featured Eclipse SDK or Scala-IDE packages and multiple version are often available. It is possible to list available Eclipse packages by issuing the command:
-
-```ShellSession
-$ nix-env -f '<nixpkgs>' -qaP -A eclipses --description
-```
-
-Once an Eclipse variant is installed, it can be run using the `eclipse` command, as expected. From within Eclipse, it is then possible to install plugins in the usual manner by either manually specifying an Eclipse update site or by installing the Marketplace Client plugin and using it to discover and install other plugins. This installation method provides an Eclipse installation that closely resemble a manually installed Eclipse.
-
-If you prefer to install plugins in a more declarative manner, then Nixpkgs also offer a number of Eclipse plugins that can be installed in an _Eclipse environment_. This type of environment is created using the function `eclipseWithPlugins` found inside the `nixpkgs.eclipses` attribute set. This function takes as argument `{ eclipse, plugins ? [], jvmArgs ? [] }` where `eclipse` is a one of the Eclipse packages described above, `plugins` is a list of plugin derivations, and `jvmArgs` is a list of arguments given to the JVM running the Eclipse. For example, say you wish to install the latest Eclipse Platform with the popular Eclipse Color Theme plugin and also allow Eclipse to use more RAM. You could then add:
-
-```nix
-packageOverrides = pkgs: {
-  myEclipse = with pkgs.eclipses; eclipseWithPlugins {
-    eclipse = eclipse-platform;
-    jvmArgs = [ "-Xmx2048m" ];
-    plugins = [ plugins.color-theme ];
-  };
-}
-```
-
-to your Nixpkgs configuration (`~/.config/nixpkgs/config.nix`) and install it by running `nix-env -f '<nixpkgs>' -iA myEclipse` and afterward run Eclipse as usual. It is possible to find out which plugins are available for installation using `eclipseWithPlugins` by running:
-
-```ShellSession
-$ nix-env -f '<nixpkgs>' -qaP -A eclipses.plugins --description
-```
-
-If there is a need to install plugins that are not available in Nixpkgs then it may be possible to define these plugins outside Nixpkgs using the `buildEclipseUpdateSite` and `buildEclipsePlugin` functions found in the `nixpkgs.eclipses.plugins` attribute set. Use the `buildEclipseUpdateSite` function to install a plugin distributed as an Eclipse update site. This function takes `{ name, src }` as argument, where `src` indicates the Eclipse update site archive. All Eclipse features and plugins within the downloaded update site will be installed. When an update site archive is not available, then the `buildEclipsePlugin` function can be used to install a plugin that consists of a pair of feature and plugin JARs. This function takes an argument `{ name, srcFeature, srcPlugin }` where `srcFeature` and `srcPlugin` are the feature and plugin JARs, respectively.
-
-Expanding the previous example with two plugins using the above functions, we have:
-
-```nix
-packageOverrides = pkgs: {
-  myEclipse = with pkgs.eclipses; eclipseWithPlugins {
-    eclipse = eclipse-platform;
-    jvmArgs = [ "-Xmx2048m" ];

-## Configuring Emacs {#sec-emacs-config}
-
-The Emacs package comes with some extra helpers to make it easier to configure. `emacs.pkgs.withPackages` allows you to manage packages from ELPA. This means that you will not have to install that packages from within Emacs. For instance, if you wanted to use `company` `counsel`, `flycheck`, `ivy`, `magit`, `projectile`, and `use-package` you could use this as a `~/.config/nixpkgs/config.nix` override:
-
-```nix
-{
-  packageOverrides = pkgs: with pkgs; {
-    myEmacs = emacs.pkgs.withPackages (epkgs: (with epkgs.melpaStablePackages; [

-      magit
-      projectile
-      use-package
-    ]));
-  }
-}
-```
-
-You can install it like any other packages via `nix-env -iA myEmacs`. However, this will only install those packages. It will not `configure` them for us. To do this, we need to provide a configuration file. Luckily, it is possible to do this from within Nix! By modifying the above example, we can make Emacs load a custom config file. The key is to create a package that provides a `default.el` file in `/share/emacs/site-start/`. Emacs knows to load this file automatically when it starts.
-
-```nix
-{

-This provides a fairly full Emacs start file. It will load in addition to the user's personal config. You can always disable it by passing `-q` to the Emacs command.
-
-Sometimes `emacs.pkgs.withPackages` is not enough, as this package set has some priorities imposed on packages (with the lowest priority assigned to Melpa Unstable, and the highest for packages manually defined in `pkgs/top-level/emacs-packages.nix`). But you can't control these priorities when some package is installed as a dependency. You can override it on a per-package-basis, providing all the required dependencies manually, but it's tedious and there is always a possibility that an unwanted dependency will sneak in through some other package. To completely override such a package, you can use `overrideScope'`.

-If `nixExtensions != null`, then all manually installed add-ons will be uninstalled from your browser profile.
-To view available enterprise policies, visit [enterprise policies](https://github.com/mozilla/policy-templates#enterprisepoliciesenabled)
-or type into the Firefox URL bar: `about:policies#documentation`.
-Nix installed add-ons do not have a valid signature, which is why signature verification is disabled. This does not compromise security because downloaded add-ons are checksummed and manual add-ons can't be installed. Also, make sure that the `name` field of `fetchFirefoxAddon` is unique. If you remove an add-on from the `nixExtensions` array, rebuild and start Firefox: the removed add-on will be completely removed with all of its settings.
-
-## Troubleshooting {#sec-firefox-troubleshooting}
-If add-ons are marked as broken or the signature is invalid, make sure you have Firefox ESR installed. Normal Firefox does not provide the ability anymore to disable signature verification for add-ons thus nix add-ons get disabled by the normal Firefox binary.
-
-If add-ons do not appear installed despite being defined in your nix configuration file, reset the local add-on state of your Firefox profile by clicking `Help -> More Troubleshooting Information -> Refresh Firefox`. This can happen if you switch from manual add-on mode to nix add-on mode and then back to manual mode and then again to nix add-on mode.

-
-In general, FUSE software are primarily developed for Linux but many of them can

-[macFUSE](https://osxfuse.github.io) to be installed outside of Nix. macFUSE
-currently isn't packaged in Nixpkgs mainly because it includes a kernel
-extension, which isn't supported by Nix outside of NixOS.

-Package maintainers may often encounter the following error when building FUSE
-packages on macOS:
-
-    checking for fuse.h... no
-    configure: error: No fuse.h found.
-
-This happens on autoconf based projects that use `AC_CHECK_HEADERS` or
-`AC_CHECK_LIBS` to detect libfuse, and will occur even when the `fuse` package
-is included in `buildInputs`. It happens because libfuse headers throw an error
-on macOS if the `FUSE_USE_VERSION` macro is undefined. Many projects do define
-`FUSE_USE_VERSION`, but only inside C source files. This results in the above
-error at configure time because the configure script would attempt to compile
-sample FUSE programs without defining `FUSE_USE_VERSION`.
-
-There are two possible solutions for this problem in Nixpkgs:
-
-1. Pass `FUSE_USE_VERSION` to the configure script by adding
-   `CFLAGS=-DFUSE_USE_VERSION=25` in `configureFlags`. The actual value would
-   have to match the definition used in the upstream source code.
-2. Remove `AC_CHECK_HEADERS` / `AC_CHECK_LIBS` for libfuse.
-
-However, a better solution might be to fix the build script upstream to use
-`PKG_CHECK_MODULES` instead. This approach wouldn't suffer from the problem that
-`AC_CHECK_HEADERS`/`AC_CHECK_LIBS` has at the price of introducing a dependency
-on pkg-config.

-# Linux kernel {#sec-linux-kernel}
-
-The Nix expressions to build the Linux kernel are in [`pkgs/os-specific/linux/kernel`](https://github.com/NixOS/nixpkgs/blob/master/pkgs/os-specific/linux/kernel).
-
-The function that builds the kernel has an argument `kernelPatches` which should be a list of `{name, patch, extraConfig}` attribute sets, where `name` is the name of the patch (which is included in the kernel’s `meta.description` attribute), `patch` is the patch itself (possibly compressed), and `extraConfig` (optional) is a string specifying extra options to be concatenated to the kernel configuration file (`.config`).
-
-The kernel derivation exports an attribute `features` specifying whether optional functionality is or isn’t enabled. This is used in NixOS to implement kernel-specific behaviour. For instance, if the kernel has the `iwlwifi` feature (i.e., has built-in support for Intel wireless chipsets), then NixOS doesn’t have to build the external `iwlwifi` package:
-
-```nix
-modulesTree = [kernel]
-  ++ pkgs.lib.optional (!kernel.features ? iwlwifi) kernelPackages.iwlwifi
-  ++ ...;
-```
-
-How to add a new (major) version of the Linux kernel to Nixpkgs:
-
-1.  Copy the old Nix expression (e.g., `linux-2.6.21.nix`) to the new one (e.g., `linux-2.6.22.nix`) and update it.
-
-2.  Add the new kernel to the `kernels` attribute set in `linux-kernels.nix` (e.g., create an attribute `kernel_2_6_22`).
-
-3.  Now we’re going to update the kernel configuration. First unpack the kernel. Then for each supported platform (`i686`, `x86_64`, `uml`) do the following:
-
-    1.  Make a copy from the old config (e.g., `config-2.6.21-i686-smp`) to the new one (e.g., `config-2.6.22-i686-smp`).
-
-    2.  Copy the config file for this platform (e.g., `config-2.6.22-i686-smp`) to `.config` in the kernel source tree.
-
-    3.  Run `make oldconfig ARCH={i386,x86_64,um}` and answer all questions. (For the uml configuration, also add `SHELL=bash`.) Make sure to keep the configuration consistent between platforms (i.e., don’t enable some feature on `i686` and disable it on `x86_64`).
-
-    4.  If needed, you can also run `make menuconfig`:
-
-        ```ShellSession
-        $ nix-env -f "<nixpkgs>" -iA ncurses
-        $ export NIX_CFLAGS_LINK=-lncurses
-        $ make menuconfig ARCH=arch
-        ```
-
-    5.  Copy `.config` over the new config file (e.g., `config-2.6.22-i686-smp`).
-
-4.  Test building the kernel: `nix-build -A linuxKernel.kernels.kernel_2_6_22`. If it compiles, ship it! For extra credit, try booting NixOS with it.
-
-5.  It may be that the new kernel requires updating the external kernel modules and kernel-dependent packages listed in the `linuxPackagesFor` function in `linux-kernels.nix` (such as the NVIDIA drivers, AUFS, etc.). If the updated packages aren’t backwards compatible with older kernels, you may need to keep the older versions around.

-# Locales {#locales}
-
-To allow simultaneous use of packages linked against different versions of `glibc` with different locale archive formats, Nixpkgs patches `glibc` to rely on `LOCALE_ARCHIVE` environment variable.
-
-On non-NixOS distributions, this variable is obviously not set. This can cause regressions in language support or even crashes in some Nixpkgs-provided programs. The simplest way to mitigate this problem is exporting the `LOCALE_ARCHIVE` variable pointing to `${glibcLocales}/lib/locale/locale-archive`. The drawback (and the reason this is not the default) is the relatively large (a hundred MiB) size of the full set of locales. It is possible to build a custom set of locales by overriding parameters `allLocales` and `locales` of the package.

-## ETags on static files served from the Nix store {#sec-nginx-etag}
-
-HTTP has a couple of different mechanisms for caching to prevent clients from having to download the same content repeatedly if a resource has not changed since the last time it was requested. When nginx is used as a server for static files, it implements the caching mechanism based on the [`Last-Modified`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Last-Modified) response header automatically; unfortunately, it works by using filesystem timestamps to determine the value of the `Last-Modified` header. This doesn't give the desired behavior when the file is in the Nix store because all file timestamps are set to 0 (for reasons related to build reproducibility).
-
-Fortunately, HTTP supports an alternative (and more effective) caching mechanism: the [`ETag`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/ETag) response header. The value of the `ETag` header specifies some identifier for the particular content that the server is sending (e.g., a hash). When a client makes a second request for the same resource, it sends that value back in an `If-None-Match` header. If the ETag value is unchanged, then the server does not need to resend the content.
-
-As of NixOS 19.09, the nginx package in Nixpkgs is patched such that when nginx serves a file out of `/nix/store`, the hash in the store path is used as the `ETag` header in the HTTP response, thus providing proper caching functionality. This happens automatically; you do not need to do modify any configuration to get this behavior.

When unpacked, it has a script called `steam` that in Ubuntu (their target distro) would go to `/usr/bin`. When run for the first time, this script copies some files to the user's home, which include another script that is the ultimate responsible for launching the steam binary, which is also in `$HOME`.

-- We don't have `/bin/bash` and many scripts point there. Same thing for `/usr/bin/python`.
-- We don't have the dynamic loader in `/lib`.
-- The `steam.sh` script in `$HOME` cannot be patched, as it is checked and rewritten by steam.
-- The steam binary cannot be patched, it's also checked.
-
-The current approach to deploy Steam in NixOS is composing a FHS-compatible chroot environment, as documented [here](http://sandervanderburg.blogspot.nl/2013/09/composing-fhs-compatible-chroot.html).

-In `nixpkgs`, urxvt is provided by the package `rxvt-unicode`. It can be configured to include your choice of plugins, reducing its closure size from the default configuration which includes all available plugins. To make use of this functionality, use an overlay or directly install an expression that overrides its configuration, such as:

-
-Alternatively, if your shell is bash or zsh and have completion enabled, simply type `nixpkgs.rxvt-unicode.plugins.<tab>`.
-
-In addition to `plugins` the options `extraDeps` and `perlDeps` can be used to install extra packages. `extraDeps` can be used, for example, to provide `xsel` (a clipboard manager) to the clipboard plugin, without installing it globally:
-
-```nix
-rxvt-unicode.override {

-}

-
-`perlDeps` is a handy way to provide Perl packages to your custom plugins (in `$HOME/.urxvt/ext`). For example, if you need `AnyEvent` you can do:
-
-```nix

-  configure = { availablePlugins, ... }: {
-    perlDeps = with perlPackages; [ AnyEvent ];
-  };
-}
-```
-
-## Packaging urxvt plugins {#sec-urxvt-pkg}
-
-Urxvt plugins resides in `pkgs/applications/misc/rxvt-unicode-plugins`. To add a new plugin, create an expression in a subdirectory and add the package to the set in `pkgs/applications/misc/rxvt-unicode-plugins/default.nix`.
-
-A plugin can be any kind of derivation, the only requirement is that it should always install perl scripts in `$out/lib/urxvt/perl`. Look for existing plugins for examples.
-
-If the plugin is itself a Perl package that needs to be imported from other plugins or scripts, add the following passthrough:
-
-```nix
-passthru.perlPackages = [ "self" ];
-```
-
-This will make the urxvt wrapper pick up the dependency and set up the Perl path accordingly.

-# X.org {#sec-xorg}
-
-The Nix expressions for the X.org packages reside in `pkgs/servers/x11/xorg/default.nix`. This file is automatically generated from lists of tarballs in an X.org release. As such it should not be modified directly; rather, you should modify the lists, the generator script or the file `pkgs/servers/x11/xorg/overrides.nix`, in which you can override or add to the derivations produced by the generator.
-
-## Katamari Tarballs {#katamari-tarballs}
-
-X.org upstream releases used to include [katamari](https://en.wiktionary.org/wiki/%E3%81%8B%E3%81%9F%E3%81%BE%E3%82%8A) releases, which included a holistic recommended version for each tarball, up until 7.7. To create a list of tarballs in a katamari release:
-
-```ShellSession
-export release="X11R7.7"
-export url="mirror://xorg/$release/src/everything/"
-cat $(PRINT_PATH=1 nix-prefetch-url $url | tail -n 1) \
-  | perl -e 'while (<>) { if (/(href|HREF)="([^"]*.bz2)"/) { print "$ENV{'url'}$2\n"; }; }' \
-  | sort > "tarballs-$release.list"
-```
-
-## Individual Tarballs {#individual-tarballs}
-
-The upstream release process for [X11R7.8](https://x.org/wiki/Releases/7.8/) does not include a planned katamari. Instead, each component of X.org is released as its own tarball. We maintain `pkgs/servers/x11/xorg/tarballs.list` as a list of tarballs for each individual package. This list includes X.org core libraries and protocol descriptions, extra newer X11 interface libraries, like `xorg.libxcb`, and classic utilities which are largely unused but still available if needed, like `xorg.imake`.
-
-## Generating Nix Expressions {#generating-nix-expressions}
-
-The generator is invoked as follows:
-
-```ShellSession
-cd pkgs/servers/x11/xorg
-<tarballs.list perl ./generate-expr-from-tarballs.pl
-```
-
-For each of the tarballs in the `.list` files, the script downloads it, unpacks it, and searches its `configure.ac` and `*.pc.in` files for dependencies. This information is used to generate `default.nix`. The generator caches downloaded tarballs between runs. Pay close attention to the `NOT FOUND: $NAME` messages at the end of the run, since they may indicate missing dependencies. (Some might be optional dependencies, however.)
-
-## Overriding the Generator {#overriding-the-generator}
-
-If the expression for a package requires derivation attributes that the generator cannot figure out automatically (say, `patches` or a `postInstall` hook), you should modify `pkgs/servers/x11/xorg/overrides.nix`.

-# darwin.linux-builder {#sec-darwin-builder}
-
-`darwin.linux-builder` provides a way to bootstrap a Linux builder on a macOS machine.
-
-This requires macOS version 12.4 or later.
-
-The builder runs on host port 31022 by default.
-You can change it by overriding `virtualisation.darwin-builder.hostPort`.
-See the [example](#sec-darwin-builder-example-flake).
-
-You will also need to be a trusted user for your Nix installation.  In other
-words, your `/etc/nix/nix.conf` should have something like:
-
-```
-extra-trusted-users = <your username goes here>
-```
-
-To launch the builder, run the following flake:
-
-```ShellSession
-$ nix run nixpkgs#darwin.linux-builder
-```
-
-That will prompt you to enter your `sudo` password:
-
-```
-+ sudo --reset-timestamp /nix/store/…-install-credentials.sh ./keys
-Password:
-```
-
-… so that it can install a private key used to `ssh` into the build server.
-After that the script will launch the virtual machine and automatically log you
-in as the `builder` user:
-
-```
-<<< Welcome to NixOS 22.11.20220901.1bd8d11 (aarch64) - ttyAMA0 >>>
-
-Run 'nixos-help' for the NixOS manual.
-
-nixos login: builder (automatic login)
-
-
-[builder@nixos:~]$
-```
-
-> Note: When you need to stop the VM, run `shutdown now` as the `builder` user.
-
-To delegate builds to the remote builder, add the following options to your
-`nix.conf` file:
-
-```
-# - Replace ${ARCH} with either aarch64 or x86_64 to match your host machine
-# - Replace ${MAX_JOBS} with the maximum number of builds (pick 4 if you're not sure)
-builders = ssh-ng://builder@linux-builder ${ARCH}-linux /etc/nix/builder_ed25519 ${MAX_JOBS} - - - c3NoLWVkMjU1MTkgQUFBQUMzTnphQzFsWkRJMU5URTVBQUFBSUpCV2N4Yi9CbGFxdDFhdU90RStGOFFVV3JVb3RpQzVxQkorVXVFV2RWQ2Igcm9vdEBuaXhvcwo=
-
-# Not strictly necessary, but this will reduce your disk utilization
-builders-use-substitutes = true
-```
-
-To allow Nix to connect to a builder not running on port 22, you will also need to create a new file at `/etc/ssh/ssh_config.d/100-linux-builder.conf`:
-
-```
-Host linux-builder
-  Hostname localhost
-  HostKeyAlias linux-builder
-  Port 31022
-```
-
-… and then restart your Nix daemon to apply the change:
-
-```ShellSession
-$ sudo launchctl kickstart -k system/org.nixos.nix-daemon

-
-Initially you should not change the builder configuration else you will not be
-able to use the binary cache. However, after you have the builder running locally
-you may use it to build a modified builder with additional storage or memory.
-
-To do this, you just need to set the `virtualisation.darwin-builder.*` parameters as
-in the example below and rebuild.
-
-```
-    darwin-builder = nixpkgs.lib.nixosSystem {
-      system = linuxSystem;
-      modules = [
-        "${nixpkgs}/nixos/modules/profiles/macos-builder.nix"

-          virtualisation.darwin-builder.workingDirectory = "/var/lib/darwin-builder";
-        }
-      ];

-You may make any other changes to your VM in this attribute set. For example,
-you could enable Docker or X11 forwarding to your Darwin host.

-# buildFHSEnv {#sec-fhs-environments}
-
-`buildFHSEnv` provides a way to build and run FHS-compatible lightweight sandboxes. It creates an isolated root filesystem with the host's `/nix/store`, so its footprint in terms of disk space is quite small. This allows you to run software which is hard or unfeasible to patch for NixOS; 3rd-party source trees with FHS assumptions, games distributed as tarballs, software with integrity checking and/or external self-updated binaries for instance.
-It uses Linux' namespaces feature to create temporary lightweight environments which are destroyed after all child processes exit, without requiring elevated privileges. It works similar to containerisation technology such as Docker or FlatPak but provides no security-relevant separation from the host system.
-
-Accepted arguments are:
-
-- `name`
-        The name of the environment and the wrapper executable.
-- `targetPkgs`
-        Packages to be installed for the main host's architecture (i.e. x86_64 on x86_64 installations). Along with libraries binaries are also installed.
-- `multiPkgs`
-        Packages to be installed for all architectures supported by a host (i.e. i686 and x86_64 on x86_64 installations). Only libraries are installed by default.
-- `multiArch`
-        Whether to install 32bit multiPkgs into the FHSEnv in 64bit environments
-- `extraBuildCommands`
-        Additional commands to be executed for finalizing the directory structure.
-- `extraBuildCommandsMulti`
-        Like `extraBuildCommands`, but executed only on multilib architectures.
-- `extraOutputsToInstall`
-        Additional derivation outputs to be linked for both target and multi-architecture packages.
-- `extraInstallCommands`
-        Additional commands to be executed for finalizing the derivation with runner script.
-- `runScript`
-        A shell command to be executed inside the sandbox. It defaults to `bash`. Command line arguments passed to the resulting wrapper are appended to this command by default.
-        This command must be escaped; i.e. `"foo app" --do-stuff --with "some file"`. See `lib.escapeShellArgs`.
-- `profile`
-        Optional script for `/etc/profile` within the sandbox.
-
-You can create a simple environment using a `shell.nix` like this:
-
-```nix
-{ pkgs ? import <nixpkgs> {} }:
-
-(pkgs.buildFHSEnv {
-  name = "simple-x11-env";
-  targetPkgs = pkgs: (with pkgs; [
-    udev
-    alsa-lib
-  ]) ++ (with pkgs.xorg; [
-    libX11
-    libXcursor
-    libXrandr
-  ]);
-  multiPkgs = pkgs: (with pkgs; [
-    udev
-    alsa-lib
-  ]);
-  runScript = "bash";
-}).env
-```
-
-Running `nix-shell` on it would drop you into a shell inside an FHS env where those libraries and binaries are available in FHS-compliant paths. Applications that expect an FHS structure (i.e. proprietary binaries) can run inside this environment without modification.
-You can build a wrapper by running your binary in `runScript`, e.g. `./bin/start.sh`. Relative paths work as expected.
-
-Additionally, the FHS builder links all relocated gsettings-schemas (the glib setup-hook moves them to `share/gsettings-schemas/${name}/glib-2.0/schemas`) to their standard FHS location. This means you don't need to wrap binaries with `wrapGAppsHook`.

-# Testers {#chap-testers}
-This chapter describes several testing builders which are available in the `testers` namespace.
-
-## `hasPkgConfigModule` {#tester-hasPkgConfigModule}
-
-Checks whether a package exposes a certain `pkg-config` module.
-
-Example:
-
-```nix
-passthru.tests.pkg-config = testers.hasPkgConfigModule {
-  package = finalAttrs.finalPackage;
-  moduleName = "libfoo";
-}
-```
-
-## `testVersion` {#tester-testVersion}
-
-Checks the command output contains the specified version
-
-Although simplistic, this test assures that the main program
-can run. While there's no substitute for a real test case,
-it does catch dynamic linking errors and such. It also provides
-some protection against accidentally building the wrong version,
-for example when using an 'old' hash in a fixed-output derivation.
-
-Examples:
-
-```nix
-passthru.tests.version = testers.testVersion { package = hello; };
-
-passthru.tests.version = testers.testVersion {
-  package = seaweedfs;
-  command = "weed version";
-};
-
-passthru.tests.version = testers.testVersion {
-  package = key;
-  command = "KeY --help";
-  # Wrong '2.5' version in the code. Drop on next version.
-  version = "2.5";
-};
-
-passthru.tests.version = testers.testVersion {
-  package = ghr;
-  # The output needs to contain the 'version' string without any prefix or suffix.
-  version = "v${version}";
-};
-```
-
-## `testBuildFailure` {#tester-testBuildFailure}
-
-Make sure that a build does not succeed. This is useful for testing testers.
-
-This returns a derivation with an override on the builder, with the following effects:
-
- - Fail the build when the original builder succeeds
- - Move `$out` to `$out/result`, if it exists (assuming `out` is the default output)
- - Save the build log to `$out/testBuildFailure.log` (same)
-
-Example:
-
-```nix
-runCommand "example" {
-  failed = testers.testBuildFailure (runCommand "fail" {} ''
-    echo ok-ish >$out
-    echo failing though
-    exit 3
-  '');
-} ''
-  grep -F 'ok-ish' $failed/result
-  grep -F 'failing though' $failed/testBuildFailure.log
-  [[ 3 = $(cat $failed/testBuildFailure.exit) ]]
-  touch $out
-'';
-```
-
-While `testBuildFailure` is designed to keep changes to the original builder's
-environment to a minimum, some small changes are inevitable.
-
- - The file `$TMPDIR/testBuildFailure.log` is present. It should not be deleted.
- - `stdout` and `stderr` are a pipe instead of a tty. This could be improved.
- - One or two extra processes are present in the sandbox during the original
-   builder's execution.
- - The derivation and output hashes are different, but not unusual.
- - The derivation includes a dependency on `buildPackages.bash` and
-   `expect-failure.sh`, which is built to include a transitive dependency on
-   `buildPackages.coreutils` and possibly more. These are not added to `PATH`
-   or any other environment variable, so they should be hard to observe.
-
-## `testEqualContents` {#tester-equalContents}
-
-Check that two paths have the same contents.
-
-Example:
-
-```nix
-testers.testEqualContents {
-  assertion = "sed -e performs replacement";
-  expected = writeText "expected" ''
-    foo baz baz
-  '';
-  actual = runCommand "actual" {
-    # not really necessary for a package that's in stdenv
-    nativeBuildInputs = [ gnused ];
-    base = writeText "base" ''
-      foo bar baz
-    '';
-  } ''
-    sed -e 's/bar/baz/g' $base >$out
-  '';
-}
-```
-
-## `testEqualDerivation` {#tester-testEqualDerivation}
-
-Checks that two packages produce the exact same build instructions.
-
-This can be used to make sure that a certain difference of configuration,
-such as the presence of an overlay does not cause a cache miss.
-
-When the derivations are equal, the return value is an empty file.
-Otherwise, the build log explains the difference via `nix-diff`.
-
-Example:
-
-```nix
-testers.testEqualDerivation
-  "The hello package must stay the same when enabling checks."
-  hello
-  (hello.overrideAttrs(o: { doCheck = true; }))
-```
-
-## `invalidateFetcherByDrvHash` {#tester-invalidateFetcherByDrvHash}
-
-Use the derivation hash to invalidate the output via name, for testing.
-
-Type: `(a@{ name, ... } -> Derivation) -> a -> Derivation`
-
-Normally, fixed output derivations can and should be cached by their output
-hash only, but for testing we want to re-fetch everytime the fetcher changes.
-
-Changes to the fetcher become apparent in the drvPath, which is a hash of
-how to fetch, rather than a fixed store path.
-By inserting this hash into the name, we can make sure to re-run the fetcher
-every time the fetcher changes.
-
-This relies on the assumption that Nix isn't clever enough to reuse its
-database of local store contents to optimize fetching.
-
-You might notice that the "salted" name derives from the normal invocation,
-not the final derivation. `invalidateFetcherByDrvHash` has to invoke the fetcher
-function twice: once to get a derivation hash, and again to produce the final
-fixed output derivation.
-
-Example:
-
-```nix
-tests.fetchgit = testers.invalidateFetcherByDrvHash fetchgit {
-  name = "nix-source";
-  url = "https://github.com/NixOS/nix";
-  rev = "9d9dbe6ed05854e03811c361a3380e09183f4f4a";
-  hash = "sha256-7DszvbCNTjpzGRmpIVAWXk20P0/XTrWZ79KSOGLrUWY=";
-};
-```
-
-## `runNixOSTest` {#tester-runNixOSTest}
-
-A helper function that behaves exactly like the NixOS `runTest`, except it also assigns this Nixpkgs package set as the `pkgs` of the test and makes the `nixpkgs.*` options read-only.
-
-If your test is part of the Nixpkgs repository, or if you need a more general entrypoint, see ["Calling a test" in the NixOS manual](https://nixos.org/manual/nixos/stable/index.html#sec-calling-nixos-tests).
-
-Example:
-
-```nix
-pkgs.testers.runNixOSTest ({ lib, ... }: {
-  name = "hello";
-  nodes.machine = { pkgs, ... }: {
-    environment.systemPackages = [ pkgs.hello ];
-  };
-  testScript = ''
-    machine.succeed("hello")
-  '';
-})
-```
-
-## `nixosTest` {#tester-nixosTest}
-
-Run a NixOS VM network test using this evaluation of Nixpkgs.
-
-NOTE: This function is primarily for external use. NixOS itself uses `make-test-python.nix` directly. Packages defined in Nixpkgs [reuse NixOS tests via `nixosTests`, plural](#ssec-nixos-tests-linking).
-
-It is mostly equivalent to the function `import ./make-test-python.nix` from the
-[NixOS manual](https://nixos.org/nixos/manual/index.html#sec-nixos-tests),
-except that the current application of Nixpkgs (`pkgs`) will be used, instead of
-letting NixOS invoke Nixpkgs anew.
-
-If a test machine needs to set NixOS options under `nixpkgs`, it must set only the
-`nixpkgs.pkgs` option.
-
-### Parameter {#tester-nixosTest-parameter}
-
-A [NixOS VM test network](https://nixos.org/nixos/manual/index.html#sec-nixos-tests), or path to it. Example:
-
-```nix
-{
-  name = "my-test";
-  nodes = {
-    machine1 = { lib, pkgs, nodes, ... }: {
-      environment.systemPackages = [ pkgs.hello ];
-      services.foo.enable = true;
-    };
-    # machine2 = ...;
-  };
-  testScript = ''
-    start_all()
-    machine1.wait_for_unit("foo.service")
-    machine1.succeed("hello | foo-send")
-  '';
-}
-```
-
-### Result {#tester-nixosTest-result}
-
-A derivation that runs the VM test.
-
-Notable attributes:
-
- * `nodes`: the evaluated NixOS configurations. Useful for debugging and exploring the configuration.
-
- * `driverInteractive`: a script that launches an interactive Python session in the context of the `testScript`.

-# Trivial builders {#chap-trivial-builders}
-
-Nixpkgs provides a couple of functions that help with building derivations. The most important one, `stdenv.mkDerivation`, has already been documented above. The following functions wrap `stdenv.mkDerivation`, making it easier to use in certain cases.
-
-## `runCommand` {#trivial-builder-runCommand}
-
-This takes three arguments, `name`, `env`, and `buildCommand`. `name` is just the name that Nix will append to the store path in the same way that `stdenv.mkDerivation` uses its `name` attribute. `env` is an attribute set specifying environment variables that will be set for this derivation. These attributes are then passed to the wrapped `stdenv.mkDerivation`. `buildCommand` specifies the commands that will be run to create this derivation. Note that you will need to create `$out` for Nix to register the command as successful.
-
-An example of using `runCommand` is provided below.
-
-```nix
-(import <nixpkgs> {}).runCommand "my-example" {} ''
-  echo My example command is running
-
-  mkdir $out
-
-  echo I can write data to the Nix store > $out/message
-
-  echo I can also run basic commands like:
-
-  echo ls
-  ls
-
-  echo whoami
-  whoami
-
-  echo date
-  date
-''
-```
-
-## `runCommandCC` {#trivial-builder-runCommandCC}
-
-This works just like `runCommand`. The only difference is that it also provides a C compiler in `buildCommand`'s environment. To minimize your dependencies, you should only use this if you are sure you will need a C compiler as part of running your command.
-
-## `runCommandLocal` {#trivial-builder-runCommandLocal}
-
-Variant of `runCommand` that forces the derivation to be built locally, it is not substituted. This is intended for very cheap commands (<1s execution time). It saves on the network round-trip and can speed up a build.
-
-::: {.note}
-This sets [`allowSubstitutes` to `false`](https://nixos.org/nix/manual/#adv-attr-allowSubstitutes), so only use `runCommandLocal` if you are certain the user will always have a builder for the `system` of the derivation. This should be true for most trivial use cases (e.g., just copying some files to a different location or adding symlinks) because there the `system` is usually the same as `builtins.currentSystem`.
-:::
-
-## `writeTextFile`, `writeText`, `writeTextDir`, `writeScript`, `writeScriptBin` {#trivial-builder-writeText}
-
-These functions write `text` to the Nix store. This is useful for creating scripts from Nix expressions. `writeTextFile` takes an attribute set and expects two arguments, `name` and `text`. `name` corresponds to the name used in the Nix store path. `text` will be the contents of the file. You can also set `executable` to true to make this file have the executable bit set.
-
-Many more commands wrap `writeTextFile` including `writeText`, `writeTextDir`, `writeScript`, and `writeScriptBin`. These are convenience functions over `writeTextFile`.
-
-Here are a few examples:
-```nix
-# Writes my-file to /nix/store/<store path>
-writeTextFile {
-  name = "my-file";
-  text = ''
-    Contents of File
-  '';
-}
-# See also the `writeText` helper function below.
-
-# Writes executable my-file to /nix/store/<store path>/bin/my-file
-writeTextFile {
-  name = "my-file";
-  text = ''
-    Contents of File
-  '';
-  executable = true;
-  destination = "/bin/my-file";
-}
-# Writes contents of file to /nix/store/<store path>
-writeText "my-file"
-  ''
-  Contents of File
-  '';
-# Writes contents of file to /nix/store/<store path>/share/my-file
-writeTextDir "share/my-file"
-  ''
-  Contents of File
-  '';
-# Writes my-file to /nix/store/<store path> and makes executable
-writeScript "my-file"
-  ''
-  Contents of File
-  '';
-# Writes my-file to /nix/store/<store path>/bin/my-file and makes executable.
-writeScriptBin "my-file"
-  ''
-  Contents of File
-  '';
-# Writes my-file to /nix/store/<store path> and makes executable.
-writeShellScript "my-file"
-  ''
-  Contents of File
-  '';
-# Writes my-file to /nix/store/<store path>/bin/my-file and makes executable.
-writeShellScriptBin "my-file"
-  ''
-  Contents of File
-  '';
-
-```
-
-## `concatTextFile`, `concatText`, `concatScript` {#trivial-builder-concatText}
-
-These functions concatenate `files` to the Nix store in a single file. This is useful for configuration files structured in lines of text. `concatTextFile` takes an attribute set and expects two arguments, `name` and `files`. `name` corresponds to the name used in the Nix store path. `files` will be the files to be concatenated. You can also set `executable` to true to make this file have the executable bit set.
-`concatText` and`concatScript` are simple wrappers over `concatTextFile`.
-
-Here are a few examples:
-```nix
-
-# Writes my-file to /nix/store/<store path>
-concatTextFile {
-  name = "my-file";
-  files = [ drv1 "${drv2}/path/to/file" ];
-}
-# See also the `concatText` helper function below.
-
-# Writes executable my-file to /nix/store/<store path>/bin/my-file
-concatTextFile {
-  name = "my-file";
-  files = [ drv1 "${drv2}/path/to/file" ];
-  executable = true;
-  destination = "/bin/my-file";
-}
-# Writes contents of files to /nix/store/<store path>
-concatText "my-file" [ file1 file2 ]
-
-# Writes contents of files to /nix/store/<store path>
-concatScript "my-file" [ file1 file2 ]
-```
-
-## `writeShellApplication` {#trivial-builder-writeShellApplication}
-
-This can be used to easily produce a shell script that has some dependencies (`runtimeInputs`). It automatically sets the `PATH` of the script to contain all of the listed inputs, sets some sanity shellopts (`errexit`, `nounset`, `pipefail`), and checks the resulting script with [`shellcheck`](https://github.com/koalaman/shellcheck).
-
-For example, look at the following code:
-
-```nix
-writeShellApplication {
-  name = "show-nixos-org";
-
-  runtimeInputs = [ curl w3m ];
-
-  text = ''
-    curl -s 'https://nixos.org' | w3m -dump -T text/html
-  '';
-}
-```
-
-Unlike with normal `writeShellScriptBin`, there is no need to manually write out `${curl}/bin/curl`, setting the PATH
-was handled by `writeShellApplication`. Moreover, the script is being checked with `shellcheck` for more strict
-validation.
-
-## `symlinkJoin` {#trivial-builder-symlinkJoin}
-
-This can be used to put many derivations into the same directory structure. It works by creating a new derivation and adding symlinks to each of the paths listed. It expects two arguments, `name`, and `paths`. `name` is the name used in the Nix store path for the created derivation. `paths` is a list of paths that will be symlinked. These paths can be to Nix store derivations or any other subdirectory contained within.
-Here is an example:
-```nix
-# adds symlinks of hello and stack to current build and prints "links added"
-symlinkJoin { name = "myexample"; paths = [ pkgs.hello pkgs.stack ]; postBuild = "echo links added"; }
-```
-This creates a derivation with a directory structure like the following:
-```
-/nix/store/sglsr5g079a5235hy29da3mq3hv8sjmm-myexample
-|-- bin
-|   |-- hello -> /nix/store/qy93dp4a3rqyn2mz63fbxjg228hffwyw-hello-2.10/bin/hello
-|   `-- stack -> /nix/store/6lzdpxshx78281vy056lbk553ijsdr44-stack-2.1.3.1/bin/stack
-`-- share
-    |-- bash-completion
-    |   `-- completions
-    |       `-- stack -> /nix/store/6lzdpxshx78281vy056lbk553ijsdr44-stack-2.1.3.1/share/bash-completion/completions/stack
-    |-- fish
-    |   `-- vendor_completions.d
-    |       `-- stack.fish -> /nix/store/6lzdpxshx78281vy056lbk553ijsdr44-stack-2.1.3.1/share/fish/vendor_completions.d/stack.fish
-...
-```
-
-## `writeReferencesToFile` {#trivial-builder-writeReferencesToFile}
-
-Writes the closure of transitive dependencies to a file.
-
-This produces the equivalent of `nix-store -q --requisites`.
-
-For example,
-
-```nix
-writeReferencesToFile (writeScriptBin "hi" ''${hello}/bin/hello'')
-```
-
-produces an output path `/nix/store/<hash>-runtime-deps` containing
-
-```nix
-/nix/store/<hash>-hello-2.10
-/nix/store/<hash>-hi
-/nix/store/<hash>-libidn2-2.3.0
-/nix/store/<hash>-libunistring-0.9.10
-/nix/store/<hash>-glibc-2.32-40
-```
-
-You can see that this includes `hi`, the original input path,
-`hello`, which is a direct reference, but also
-the other paths that are indirectly required to run `hello`.
-
-## `writeDirectReferencesToFile` {#trivial-builder-writeDirectReferencesToFile}
-
-Writes the set of references to the output file, that is, their immediate dependencies.
-
-This produces the equivalent of `nix-store -q --references`.
-
-For example,
-
-```nix
-writeDirectReferencesToFile (writeScriptBin "hi" ''${hello}/bin/hello'')
-```
-
-produces an output path `/nix/store/<hash>-runtime-references` containing
-
-```nix
-/nix/store/<hash>-hello-2.10
-```
-
-but none of `hello`'s dependencies because those are not referenced directly
-by `hi`'s output.

-- Use 2 spaces of indentation per indentation level in Nix expressions, 4 spaces in shell scripts.
-
-- Do not use tab characters, i.e. configure your editor to use soft tabs. For instance, use `(setq-default indent-tabs-mode nil)` in Emacs. Everybody has different tab settings so it’s asking for trouble.

-  # A short list.
-  list = [ elem1 elem2 elem3 ];
-
-  # A short set.
-  attrs = { x = 1280; y = 1024; };
-  ```
-
-- Breaking in the middle of a function argument can give hard-to-read code, like

-  ```nix
-  someFunction { x = 1280;
-    y = 1024; } otherArg
-    yetAnotherArg
-  ```
-
-  (especially if the argument is very large, spanning multiple lines).
-
-  Better:
-
-  ```nix
-  someFunction
-    { x = 1280; y = 1024; }
-    otherArg
-    yetAnotherArg
-  ```
-

-  ```
-
-  or
-
-  ```nix
-  { stdenv, fetchurl, perl, ... }: ...

-
-  For functions that are truly generic in the number of arguments (such as wrappers around `mkDerivation`) that have some required arguments, you should write them using an `@`-pattern:
-
-  ```nix
-  { stdenv, doCoverageAnalysis ? false, ... } @ args:
-
-  stdenv.mkDerivation (args // {
-    ... if doCoverageAnalysis then "bla" else "" ...

-  ```nix
-  rev = version;
-  ```
-
-  instead of
-
-  ```nix
-  rev = "${version}";
-  ```
-
-- Building lists conditionally _should_ be done with `lib.optional(s)` instead of using `if cond then [ ... ] else null` or `if cond then [ ... ] else [ ]`.
-
-  ```nix
-  buildInputs = lib.optional stdenv.isDarwin iconv;
-  ```
-
-  instead of
-
-  ```nix
-  buildInputs = if stdenv.isDarwin then [ iconv ] else null;
-  ```
-
-  As an exception, an explicit conditional expression with null can be used when fixing a important bug without triggering a mass rebuild.
-  If this is done a follow up pull request _should_ be created to change the code to `lib.optional(s)`.
-
-- Arguments should be listed in the order they are used, with the exception of `lib`, which always goes first.
-
-## Package naming {#sec-package-naming}
-
-The key words _must_, _must not_, _required_, _shall_, _shall not_, _should_, _should not_, _recommended_, _may_, and _optional_ in this section are to be interpreted as described in [RFC 2119](https://tools.ietf.org/html/rfc2119). Only _emphasized_ words are to be interpreted in this way.
-
-In Nixpkgs, there are generally three different names associated with a package:
-
-- The `pname` attribute of the derivation. This is what most users see, in particular when using `nix-env`.
-
-- The variable name used for the instantiated package in `all-packages.nix`, and when passing it as a dependency to other functions. Typically this is called the _package attribute name_. This is what Nix expression authors see. It can also be used when installing using `nix-env -iA`.
-
-- The filename for (the directory containing) the Nix expression.
-
-Most of the time, these are the same. For instance, the package `e2fsprogs` has a `pname` attribute `"e2fsprogs"`, is bound to the variable name `e2fsprogs` in `all-packages.nix`, and the Nix expression is in `pkgs/os-specific/linux/e2fsprogs/default.nix`.
-
-There are a few naming guidelines:
-
-- The `pname` attribute _should_ be identical to the upstream package name.
-
-- The `pname` and the `version` attribute _must not_ contain uppercase letters — e.g., `"mplayer" instead of `"MPlayer"`.
-
-- The `version` attribute _must_ start with a digit e.g`"0.3.1rc2".
-
-- If a package is a commit from a repository without a version assigned, then the `version` attribute _should_ be the latest upstream version preceding that commit, followed by `-unstable-` and the date of the (fetched) commit. The date _must_ be in `"YYYY-MM-DD"` format.
-
-Example: Given a project had its latest releases `2.2` in November 2021, and `3.0` in January 2022, a commit authored on March 15, 2022 for an upcoming bugfix release `2.2.1` would have `version = "2.2-unstable-2022-03-15"`.
-
-- Dashes in the package `pname` _should_ be preserved in new variable names, rather than converted to underscores or camel cased — e.g., `http-parser` instead of `http_parser` or `httpParser`. The hyphenated style is preferred in all three package names.
-
-- If there are multiple versions of a package, this _should_ be reflected in the variable names in `all-packages.nix`, e.g. `json-c_0_9` and `json-c_0_11`. If there is an obvious “default” version, make an attribute like `json-c = json-c_0_9;`. See also [](#sec-versioning)
-
-## File naming and organisation {#sec-organisation}
-
-Names of files and directories should be in lowercase, with dashes between words — not in camel case. For instance, it should be `all-packages.nix`, not `allPackages.nix` or `AllPackages.nix`.
-
-### Hierarchy {#sec-hierarchy}
-
-Each package should be stored in its own directory somewhere in the `pkgs/` tree, i.e. in `pkgs/category/subcategory/.../pkgname`. Below are some rules for picking the right category for a package. Many packages fall under several categories; what matters is the _primary_ purpose of a package. For example, the `libxml2` package builds both a library and some tools; but it’s a library foremost, so it goes under `pkgs/development/libraries`.
-
-When in doubt, consider refactoring the `pkgs/` tree, e.g. creating new categories or splitting up an existing category.

-
-### Versioning {#sec-versioning}
-
-Because every version of a package in Nixpkgs creates a potential maintenance burden, old versions of a package should not be kept unless there is a good reason to do so. For instance, Nixpkgs contains several versions of GCC because other packages don’t build with the latest version of GCC. Other examples are having both the latest stable and latest pre-release version of a package, or to keep several major releases of an application that differ significantly in functionality.
-
-If there is only one version of a package, its Nix expression should be named `e2fsprogs/default.nix`. If there are multiple versions, this should be reflected in the filename, e.g. `e2fsprogs/1.41.8.nix` and `e2fsprogs/1.41.9.nix`. The version in the filename should leave out unnecessary detail. For instance, if we keep the latest Firefox 2.0.x and 3.5.x versions in Nixpkgs, they should be named `firefox/2.0.nix` and `firefox/3.5.nix`, respectively (which, at a given point, might contain versions `2.0.0.20` and `3.5.4`). If a version requires many auxiliary files, you can use a subdirectory for each version, e.g. `firefox/2.0/default.nix` and `firefox/3.5/default.nix`.
-
-All versions of a package _must_ be included in `all-packages.nix` to make sure that they evaluate correctly.
-
-## Fetching Sources {#sec-sources}
-
-There are multiple ways to fetch a package source in nixpkgs. The general guideline is that you should package reproducible sources with a high degree of availability. Right now there is only one fetcher which has mirroring support and that is `fetchurl`. Note that you should also prefer protocols which have a corresponding proxy environment variable.
-
-You can find many source fetch helpers in `pkgs/build-support/fetch*`.
-
-In the file `pkgs/top-level/all-packages.nix` you can find fetch helpers, these have names on the form `fetchFrom*`. The intention of these are to provide snapshot fetches but using the same api as some of the version controlled fetchers from `pkgs/build-support/`. As an example going from bad to good:
-
-- Bad: Uses `git://` which won't be proxied.
-
-  ```nix
-  src = fetchgit {
-    url = "git@github.com:NixOS/nix.git"
-    url = "git://github.com/NixOS/nix.git";
-    rev = "1f795f9f44607cc5bec70d1300150bfefcef2aae";
-    hash = "sha256-7D4m+saJjbSFP5hOwpQq2FGR2rr+psQMTcyb1ZvtXsQ=";
-  }
-  ```
-
-- Better: This is ok, but an archive fetch will still be faster.
-
-  ```nix
-  src = fetchgit {
-    url = "https://github.com/NixOS/nix.git";
-    rev = "1f795f9f44607cc5bec70d1300150bfefcef2aae";
-    hash = "sha256-7D4m+saJjbSFP5hOwpQq2FGR2rr+psQMTcyb1ZvtXsQ=";
-  }
-  ```
-
-- Best: Fetches a snapshot archive and you get the rev you want.
-
-  ```nix
-  src = fetchFromGitHub {
-    owner = "NixOS";
-    repo = "nix";
-    rev = "1f795f9f44607cc5bec70d1300150bfefcef2aae";
-    hash = "sha256-7D4m+saJjbSFP5hOwpQq2FGR2rr+psQMTcyb1ZvtXsQ=";
-  }
-  ```
-
-When fetching from GitHub, commits must always be referenced by their full commit hash. This is because GitHub shares commit hashes among all forks and returns `404 Not Found` when a short commit hash is ambiguous. It already happens for some short, 6-character commit hashes in `nixpkgs`.
-It is a practical vector for a denial-of-service attack by pushing large amounts of auto generated commits into forks and was already [demonstrated against GitHub Actions Beta](https://blog.teddykatz.com/2019/11/12/github-actions-dos.html).
-
-Find the value to put as `hash` by running `nix-shell -p nix-prefetch-github --run "nix-prefetch-github --rev 1f795f9f44607cc5bec70d1300150bfefcef2aae NixOS nix"`.
-
-## Obtaining source hash {#sec-source-hashes}
-
-Preferred source hash type is sha256. There are several ways to get it.
-
-1. Prefetch URL (with `nix-prefetch-XXX URL`, where `XXX` is one of `url`, `git`, `hg`, `cvs`, `bzr`, `svn`). Hash is printed to stdout.
-
-2. Prefetch by package source (with `nix-prefetch-url '<nixpkgs>' -A PACKAGE.src`, where `PACKAGE` is package attribute name). Hash is printed to stdout.
-
-    This works well when you've upgraded existing package version and want to find out new hash, but is useless if package can't be accessed by attribute or package has multiple sources (`.srcs`, architecture-dependent sources, etc).
-
-3. Upstream provided hash: use it when upstream provides `sha256` or `sha512` (when upstream provides `md5`, don't use it, compute `sha256` instead).
-
-    A little nuance is that `nix-prefetch-*` tools produce hash encoded with `base32`, but upstream usually provides hexadecimal (`base16`) encoding. Fetchers understand both formats. Nixpkgs does not standardize on any one format.
-
-    You can convert between formats with nix-hash, for example:
-
-    ```ShellSession
-    $ nix-hash --type sha256 --to-base32 HASH
-    ```
-
-4. Extracting hash from local source tarball can be done with `sha256sum`. Use `nix-prefetch-url file:///path/to/tarball` if you want base32 hash.
-
-5. Fake hash: set the hash to one of
-
-   - `""`
-   - `lib.fakeHash`
-   - `lib.fakeSha256`
-   - `lib.fakeSha512`
-
-   in the package expression, attempt build and extract correct hash from error messages.
-
-   ::: {.warning}
-   You must use one of these four fake hashes and not some arbitrarily-chosen hash.
-
-   See [](#sec-source-hashes-security).
-   :::
-
-    This is last resort method when reconstructing source URL is non-trivial and `nix-prefetch-url -A` isn’t applicable (for example, [one of `kodi` dependencies](https://github.com/NixOS/nixpkgs/blob/d2ab091dd308b99e4912b805a5eb088dd536adb9/pkgs/applications/video/kodi/default.nix#L73)). The easiest way then would be replace hash with a fake one and rebuild. Nix build will fail and error message will contain desired hash.
-
-
-### Obtaining hashes securely {#sec-source-hashes-security}
-
-Let's say Man-in-the-Middle (MITM) sits close to your network. Then instead of fetching source you can fetch malware, and instead of source hash you get hash of malware. Here are security considerations for this scenario:
-
-- `http://` URLs are not secure to prefetch hash from;
-
-- hashes from upstream (in method 3) should be obtained via secure protocol;
-
-- `https://` URLs are secure in methods 1, 2, 3;
-
-- `https://` URLs are secure in method 5 *only if* you use one of the listed fake hashes. If you use any other hash, `fetchurl` will pass `--insecure` to `curl` and may then degrade to HTTP in case of TLS certificate expiration.
-
-## Patches {#sec-patches}
-
-Patches available online should be retrieved using `fetchpatch`.
-
-```nix
-patches = [
-  (fetchpatch {
-    name = "fix-check-for-using-shared-freetype-lib.patch";
-    url = "http://git.ghostscript.com/?p=ghostpdl.git;a=patch;h=8f5d285";
-    hash = "sha256-uRcxaCjd+WAuGrXOmGfFeu79cUILwkRdBu48mwcBE7g=";
-  })
-];
-```
-
-Otherwise, you can add a `.patch` file to the `nixpkgs` repository. In the interest of keeping our maintenance burden to a minimum, only patches that are unique to `nixpkgs` should be added in this way.
-
-If a patch is available online but does not cleanly apply, it can be modified in some fixed ways by using additional optional arguments for `fetchpatch`. Check [](#fetchpatch) for details.
-
-```nix
-patches = [ ./0001-changes.patch ];
-```
-
-If you do need to do create this sort of patch file, one way to do so is with git:
-
-1. Move to the root directory of the source code you're patching.
-
-    ```ShellSession
-    $ cd the/program/source
-    ```
-
-2. If a git repository is not already present, create one and stage all of the source files.
-
-    ```ShellSession
-    $ git init
-    $ git add .
-    ```
-
-3. Edit some files to make whatever changes need to be included in the patch.
-
-4. Use git to create a diff, and pipe the output to a patch file:
-
-    ```ShellSession
-    $ git diff -a > nixpkgs/pkgs/the/package/0001-changes.patch
-    ```
-
-## Package tests {#sec-package-tests}
-
-Tests are important to ensure quality and make reviews and automatic updates easy.
-
-The following types of tests exists:
-
-* [NixOS **module tests**](https://nixos.org/manual/nixos/stable/#sec-nixos-tests), which spawn one or more NixOS VMs. They exercise both NixOS modules and the packaged programs used within them. For example, a NixOS module test can start a web server VM running the `nginx` module, and a client VM running `curl` or a graphical `firefox`, and test that they can talk to each other and display the correct content.
-* Nix **package tests** are a lightweight alternative to NixOS module tests. They should be used to create simple integration tests for packages, but cannot test NixOS services, and some programs with graphical user interfaces may also be difficult to test with them.
-* The **`checkPhase` of a package**, which should execute the unit tests that are included in the source code of a package.
-
-Here in the nixpkgs manual we describe mostly _package tests_; for _module tests_ head over to the corresponding [section in the NixOS manual](https://nixos.org/manual/nixos/stable/#sec-nixos-tests).
-
-### Writing inline package tests {#ssec-inline-package-tests-writing}
-
-For very simple tests, they can be written inline:
-
-```nix
-{ …, yq-go }:
-
-buildGoModule rec {
-  …
-
-  passthru.tests = {
-    simple = runCommand "${pname}-test" {} ''
-      echo "test: 1" | ${yq-go}/bin/yq eval -j > $out
-      [ "$(cat $out | tr -d $'\n ')" = '{"test":1}' ]
-    '';
-  };
-}
-```
-
-### Writing larger package tests {#ssec-package-tests-writing}
-
-This is an example using the `phoronix-test-suite` package with the current best practices.
-
-Add the tests in `passthru.tests` to the package definition like this:
-
-```nix
-{ stdenv, lib, fetchurl, callPackage }:
-
-stdenv.mkDerivation {
-  …
-
-  passthru.tests = {
-    simple-execution = callPackage ./tests.nix { };
-  };
-
-  meta = { … };
-}
-```
-
-Create `tests.nix` in the package directory:
-
-```nix
-{ runCommand, phoronix-test-suite }:
-
-let
-  inherit (phoronix-test-suite) pname version;
-in
-
-runCommand "${pname}-tests" { meta.timeout = 60; }
-  ''
-    # automatic initial setup to prevent interactive questions
-    ${phoronix-test-suite}/bin/phoronix-test-suite enterprise-setup >/dev/null
-    # get version of installed program and compare with package version
-    if [[ `${phoronix-test-suite}/bin/phoronix-test-suite version` != *"${version}"*  ]]; then
-      echo "Error: program version does not match package version"
-      exit 1
-    fi
-    # run dummy command
-    ${phoronix-test-suite}/bin/phoronix-test-suite dummy_module.dummy-command >/dev/null
-    # needed for Nix to register the command as successful
-    touch $out
-  ''
-```
-
-### Running package tests {#ssec-package-tests-running}
-
-You can run these tests with:
-
-```ShellSession
-$ cd path/to/nixpkgs
-$ nix-build -A phoronix-test-suite.tests
-```
-
-### Examples of package tests {#ssec-package-tests-examples}
-
-Here are examples of package tests:
-
-- [Jasmin compile test](https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/compilers/jasmin/test-assemble-hello-world/default.nix)
-- [Lobster compile test](https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/compilers/lobster/test-can-run-hello-world.nix)
-- [Spacy annotation test](https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/python-modules/spacy/annotation-test/default.nix)
-- [Libtorch test](https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/libraries/science/math/libtorch/test/default.nix)
-- [Multiple tests for nanopb](https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/libraries/nanopb/default.nix)
-
-### Linking NixOS module tests to a package {#ssec-nixos-tests-linking}
-
-Like [package tests](#ssec-package-tests-writing) as shown above, [NixOS module tests](https://nixos.org/manual/nixos/stable/#sec-nixos-tests) can also be linked to a package, so that the tests can be easily run when changing the related package.
-
-For example, assuming we're packaging `nginx`, we can link its module test via `passthru.tests`:
-
-```nix
-{ stdenv, lib, nixosTests }:
-
-stdenv.mkDerivation {
-  ...
-
-  passthru.tests = {
-    nginx = nixosTests.nginx;
-  };
-
-  ...
-}
-```
-
-### Import From Derivation {#ssec-import-from-derivation}
-
-Import From Derivation (IFD) is disallowed in Nixpkgs for performance reasons:
-[Hydra] evaluates the entire package set, and sequential builds during evaluation would increase evaluation times to become impractical.
-
-[Hydra]: https://github.com/NixOS/hydra
-
-Import From Derivation can be worked around in some cases by committing generated intermediate files to version control and reading those instead.
-
-<!-- TODO: remove the following and link to Nix manual once https://github.com/NixOS/nix/pull/7332 is merged -->

-## Syntax {#sec-contributing-markup}
-
-As per [RFC 0072](https://github.com/NixOS/rfcs/pull/72), all new documentation content should be written in [CommonMark](https://commonmark.org/) Markdown dialect.
-
-Additional syntax extensions are available, all of which can be used in NixOS option documentation. The following extensions are currently used:
-
-- []{#ssec-contributing-markup-anchors}
-  Explicitly defined **anchors** on headings, to allow linking to sections. These should be always used, to ensure the anchors can be linked even when the heading text changes, and to prevent conflicts between [automatically assigned identifiers](https://github.com/jgm/commonmark-hs/blob/master/commonmark-extensions/test/auto_identifiers.md).
-
-  It uses the widely compatible [header attributes](https://github.com/jgm/commonmark-hs/blob/master/commonmark-extensions/test/attributes.md) syntax:
-
-  ```markdown
-  ## Syntax {#sec-contributing-markup}
-  ```
-
-  ::: {.note}
-  NixOS option documentation does not support headings in general.
-  :::
-
-- []{#ssec-contributing-markup-anchors-inline}
-  **Inline anchors**, which allow linking arbitrary place in the text (e.g. individual list items, sentences…).

-  They are defined using a hybrid of the link syntax with the attributes syntax known from headings, called [bracketed spans](https://github.com/jgm/commonmark-hs/blob/master/commonmark-extensions/test/bracketed_spans.md):
-
-  ```markdown
-  - []{#ssec-gnome-hooks-glib} `glib` setup hook will populate `GSETTINGS_SCHEMAS_PATH` and then `wrapGAppsHook` will prepend it to `XDG_DATA_DIRS`.
-  ```
-
-- []{#ssec-contributing-markup-automatic-links}
-  If you **omit a link text** for a link pointing to a section, the text will be substituted automatically. For example, `[](#chap-contributing)` will result in [](#chap-contributing).
-
-  This syntax is taken from [MyST](https://myst-parser.readthedocs.io/en/latest/using/syntax.html#targets-and-cross-referencing).
-
-- []{#ssec-contributing-markup-inline-roles}
-  If you want to link to a man page, you can use `` {manpage}`nix.conf(5)` ``, which will turn into {manpage}`nix.conf(5)`. The references will turn into links when a mapping exists in {file}`doc/manpage-urls.json`.
-
-  A few markups for other kinds of literals are also available:
-
-  - `` {command}`rm -rfi` `` turns into {command}`rm -rfi`
-  - `` {env}`XDG_DATA_DIRS` `` turns into {env}`XDG_DATA_DIRS`
-  - `` {file}`/etc/passwd` `` turns into {file}`/etc/passwd`
-  - `` {option}`networking.useDHCP` `` turns into {option}`networking.useDHCP`
-  - `` {var}`/etc/passwd` `` turns into {var}`/etc/passwd`
-
-  These literal kinds are used mostly in NixOS option documentation.
-
-  This syntax is taken from [MyST](https://myst-parser.readthedocs.io/en/latest/syntax/syntax.html#roles-an-in-line-extension-point). Though, the feature originates from [reStructuredText](https://www.sphinx-doc.org/en/master/usage/restructuredtext/roles.html#role-manpage) with slightly different syntax.
-
-- []{#ssec-contributing-markup-admonitions}
-  **Admonitions**, set off from the text to bring attention to something.
-
-  It uses pandoc’s [fenced `div`s syntax](https://github.com/jgm/commonmark-hs/blob/master/commonmark-extensions/test/fenced_divs.md):
-
-  ```markdown
-  ::: {.warning}
-  This is a warning
-  :::
-  ```
-
-  which renders as
-
-  > ::: {.warning}
-  > This is a warning.

-
-  The following are supported:

-# Quick Start to Adding a Package {#chap-quick-start}
-
-To add a package to Nixpkgs:
-
-1. Checkout the Nixpkgs source tree:
-
-   ```ShellSession
-   $ git clone https://github.com/NixOS/nixpkgs
-   $ cd nixpkgs
-   ```
-
-2. Find a good place in the Nixpkgs tree to add the Nix expression for your package. For instance, a library package typically goes into `pkgs/development/libraries/pkgname`, while a web browser goes into `pkgs/applications/networking/browsers/pkgname`. See [](#sec-organisation) for some hints on the tree organisation. Create a directory for your package, e.g.
-
-   ```ShellSession
-   $ mkdir pkgs/development/libraries/libfoo
-   ```
-
-3. In the package directory, create a Nix expression — a piece of code that describes how to build the package. In this case, it should be a _function_ that is called with the package dependencies as arguments, and returns a build of the package in the Nix store. The expression should usually be called `default.nix`.
-
-   ```ShellSession
-   $ emacs pkgs/development/libraries/libfoo/default.nix
-   $ git add pkgs/development/libraries/libfoo/default.nix
-   ```
-
-   You can have a look at the existing Nix expressions under `pkgs/` to see how it’s done. Here are some good ones:
-
-   - GNU Hello: [`pkgs/applications/misc/hello/default.nix`](https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/misc/hello/default.nix). Trivial package, which specifies some `meta` attributes which is good practice.
-
-   - GNU cpio: [`pkgs/tools/archivers/cpio/default.nix`](https://github.com/NixOS/nixpkgs/blob/master/pkgs/tools/archivers/cpio/default.nix). Also a simple package. The generic builder in `stdenv` does everything for you. It has no dependencies beyond `stdenv`.
-
-   - GNU Multiple Precision arithmetic library (GMP): [`pkgs/development/libraries/gmp/5.1.x.nix`](https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/libraries/gmp/5.1.x.nix). Also done by the generic builder, but has a dependency on `m4`.
-
-   - Pan, a GTK-based newsreader: [`pkgs/applications/networking/newsreaders/pan/default.nix`](https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/networking/newsreaders/pan/default.nix). Has an optional dependency on `gtkspell`, which is only built if `spellCheck` is `true`.
-
-   - Apache HTTPD: [`pkgs/servers/http/apache-httpd/2.4.nix`](https://github.com/NixOS/nixpkgs/blob/master/pkgs/servers/http/apache-httpd/2.4.nix). A bunch of optional features, variable substitutions in the configure flags, a post-install hook, and miscellaneous hackery.
-
-   - buildMozillaMach: [`pkgs/applications/networking/browser/firefox/common.nix`](https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/networking/browsers/firefox/common.nix). A reusable build function for Firefox, Thunderbird and Librewolf.
-
-   - JDiskReport, a Java utility: [`pkgs/tools/misc/jdiskreport/default.nix`](https://github.com/NixOS/nixpkgs/blob/master/pkgs/tools/misc/jdiskreport/default.nix). Nixpkgs doesn’t have a decent `stdenv` for Java yet so this is pretty ad-hoc.
-
-   - XML::Simple, a Perl module: [`pkgs/top-level/perl-packages.nix`](https://github.com/NixOS/nixpkgs/blob/master/pkgs/top-level/perl-packages.nix) (search for the `XMLSimple` attribute). Most Perl modules are so simple to build that they are defined directly in `perl-packages.nix`; no need to make a separate file for them.
-
-   - Adobe Reader: [`pkgs/applications/misc/adobe-reader/default.nix`](https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/misc/adobe-reader/default.nix). Shows how binary-only packages can be supported. In particular the [builder](https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/misc/adobe-reader/builder.sh) uses `patchelf` to set the RUNPATH and ELF interpreter of the executables so that the right libraries are found at runtime.
-
-   Some notes:
-
-   - All [`meta`](#chap-meta) attributes are optional, but it’s still a good idea to provide at least the `description`, `homepage` and [`license`](#sec-meta-license).
-
-   - You can use `nix-prefetch-url url` to get the SHA-256 hash of source distributions. There are similar commands as `nix-prefetch-git` and `nix-prefetch-hg` available in `nix-prefetch-scripts` package.
-
-   - A list of schemes for `mirror://` URLs can be found in [`pkgs/build-support/fetchurl/mirrors.nix`](https://github.com/NixOS/nixpkgs/blob/master/pkgs/build-support/fetchurl/mirrors.nix).
-
-   The exact syntax and semantics of the Nix expression language, including the built-in function, are described in the Nix manual in the [chapter on writing Nix expressions](https://hydra.nixos.org/job/nix/trunk/tarball/latest/download-by-type/doc/manual/#chap-writing-nix-expressions).
-
-4. Add a call to the function defined in the previous step to [`pkgs/top-level/all-packages.nix`](https://github.com/NixOS/nixpkgs/blob/master/pkgs/top-level/all-packages.nix) with some descriptive name for the variable, e.g. `libfoo`.
-
-   ```ShellSession
-   $ emacs pkgs/top-level/all-packages.nix
-   ```
-
-   The attributes in that file are sorted by category (like “Development / Libraries”) that more-or-less correspond to the directory structure of Nixpkgs, and then by attribute name.
-
-5. To test whether the package builds, run the following command from the root of the nixpkgs source tree:
-
-   ```ShellSession
-   $ nix-build -A libfoo
-   ```
-
-   where `libfoo` should be the variable name defined in the previous step. You may want to add the flag `-K` to keep the temporary build directory in case something fails. If the build succeeds, a symlink `./result` to the package in the Nix store is created.
-
-6. If you want to install the package into your profile (optional), do
-
-   ```ShellSession
-   $ nix-env -f . -iA libfoo
-   ```
-
-7. Optionally commit the new package and open a pull request [to nixpkgs](https://github.com/NixOS/nixpkgs/pulls), or use [the Patches category](https://discourse.nixos.org/t/about-the-patches-category/477) on Discourse for sending a patch without a GitHub account.

-# Reviewing contributions {#chap-reviewing-contributions}
-
-::: {.warning}
-The following section is a draft, and the policy for reviewing is still being discussed in issues such as [#11166](https://github.com/NixOS/nixpkgs/issues/11166) and [#20836](https://github.com/NixOS/nixpkgs/issues/20836).
-:::
-
-The Nixpkgs project receives a fairly high number of contributions via GitHub pull requests. Reviewing and approving these is an important task and a way to contribute to the project.
-
-The high change rate of Nixpkgs makes any pull request that remains open for too long subject to conflicts that will require extra work from the submitter or the merger. Reviewing pull requests in a timely manner and being responsive to the comments is the key to avoid this issue. GitHub provides sort filters that can be used to see the [most recently](https://github.com/NixOS/nixpkgs/pulls?q=is%3Apr+is%3Aopen+sort%3Aupdated-desc) and the [least recently](https://github.com/NixOS/nixpkgs/pulls?q=is%3Apr+is%3Aopen+sort%3Aupdated-asc) updated pull requests. We highly encourage looking at [this list of ready to merge, unreviewed pull requests](https://github.com/NixOS/nixpkgs/pulls?q=is%3Apr+is%3Aopen+review%3Anone+status%3Asuccess+-label%3A%222.status%3A+work-in-progress%22+no%3Aproject+no%3Aassignee+no%3Amilestone).
-
-When reviewing a pull request, please always be nice and polite. Controversial changes can lead to controversial opinions, but it is important to respect every community member and their work.
-
-GitHub provides reactions as a simple and quick way to provide feedback to pull requests or any comments. The thumb-down reaction should be used with care and if possible accompanied with some explanation so the submitter has directions to improve their contribution.
-
-Pull request reviews should include a list of what has been reviewed in a comment, so other reviewers and mergers can know the state of the review.
-
-All the review template samples provided in this section are generic and meant as examples. Their usage is optional and the reviewer is free to adapt them to their liking.
-
-## Package updates {#reviewing-contributions-package-updates}
-
-A package update is the most trivial and common type of pull request. These pull requests mainly consist of updating the version part of the package name and the source hash.
-
-It can happen that non-trivial updates include patches or more complex changes.
-
-Reviewing process:
-
-- Ensure that the package versioning fits the guidelines.
-- Ensure that the commit text fits the guidelines.
-- Ensure that the package maintainers are notified.
-  - [CODEOWNERS](https://help.github.com/articles/about-codeowners) will make GitHub notify users based on the submitted changes, but it can happen that it misses some of the package maintainers.
-- Ensure that the meta field information is correct.
-  - License can change with version updates, so it should be checked to match the upstream license.
-  - If the package has no maintainer, a maintainer must be set. This can be the update submitter or a community member that accepts to take maintainership of the package.
-- Ensure that the code contains no typos.
-- Building the package locally.
-  - pull requests are often targeted to the master or staging branch, and building the pull request locally when it is submitted can trigger many source builds.
-  - It is possible to rebase the changes on nixos-unstable or nixpkgs-unstable for easier review by running the following commands from a nixpkgs clone.
-
-    ```ShellSession
-    $ git fetch origin nixos-unstable
-    $ git fetch origin pull/PRNUMBER/head
-    $ git rebase --onto nixos-unstable BASEBRANCH FETCH_HEAD
-    ```
-
-    - The first command fetches the nixos-unstable branch.
-    - The second command fetches the pull request changes, `PRNUMBER` is the number at the end of the pull request title and `BASEBRANCH` the base branch of the pull request.
-    - The third command rebases the pull request changes to the nixos-unstable branch.
-  - The [nixpkgs-review](https://github.com/Mic92/nixpkgs-review) tool can be used to review a pull request content in a single command. `PRNUMBER` should be replaced by the number at the end of the pull request title. You can also provide the full github pull request url.
-
-    ```ShellSession
-    $ nix-shell -p nixpkgs-review --run "nixpkgs-review pr PRNUMBER"
-    ```
-- Running every binary.
-
-Sample template for a package update review is provided below.

-## Individual maintainer list {#reviewing-contributions-individual-maintainer-list}
-
-When adding users to `maintainers/maintainer-list.nix`, the following
-checks should be performed:
-
--   If the user has specified a GPG key, verify that the commit is
-    signed by their key.
-
-    First, validate that the commit adding the maintainer is signed by
-    the key the maintainer listed. Check out the pull request and
-    compare its signing key with the listed key in the commit.
-
-    If the commit is not signed or it is signed by a different user, ask
-    them to either recommit using that key or to remove their key
-    information.
-
-    Given a maintainer entry like this:
-
-    ``` nix
-    {
-      example = {
-        email = "user@example.com";
-        name = "Example User";
-        keys = [{
-          fingerprint = "0000 0000 2A70 6423 0AED  3C11 F04F 7A19 AAA6 3AFE";
-        }];
-      }
-    };
-    ```
-
-    First receive their key from a keyserver:
-
-        $ gpg --recv-keys 0xF04F7A19AAA63AFE
-        gpg: key 0xF04F7A19AAA63AFE: public key "Example <user@example.com>" imported
-        gpg: Total number processed: 1
-        gpg:               imported: 1
-
-    Then check the commit is signed by that key:
-
-        $ git log --show-signature
-        commit b87862a4f7d32319b1de428adb6cdbdd3a960153
-        gpg: Signature made Wed Mar 12 13:32:24 2003 +0000
-        gpg:                using RSA key 000000002A7064230AED3C11F04F7A19AAA63AFE
-        gpg: Good signature from "Example User <user@example.com>
-        Author: Example User <user@example.com>
-        Date:   Wed Mar 12 13:32:24 2003 +0000
-
-            maintainers: adding example
-
-    and validate that there is a `Good signature` and the printed key
-    matches the user's submitted key.
-
-    Note: GitHub's "Verified" label does not display the user's full key
-    fingerprint, and should not be used for validating the key matches.
-
--   If the user has specified a `github` account name, ensure they have
-    also specified a `githubId` and verify the two match.
-
-    Maintainer entries that include a `github` field must also include
-    their `githubId`. People can and do change their GitHub name
-    frequently, and the ID is used as the official and stable identity
-    of the maintainer.
-
-    Given a maintainer entry like this:
-
-    ``` nix
-    {
-      example = {
-        email = "user@example.com";
-        name = "Example User";
-        github = "ghost";
-        githubId = 10137;
-      }
-    };
-    ```
-
-    First, make sure that the listed GitHub handle matches the author of
-    the commit.
-
-    Then, visit the URL `https://api.github.com/users/ghost` and
-    validate that the `id` field matches the provided `githubId`.
-
-## Maintainer teams {#reviewing-contributions-maintainer-teams}
-
-Feel free to create a new maintainer team in `maintainers/team-list.nix`
-when a group is collectively responsible for a collection of packages.
-Use taste and personal judgement when deciding if a team is warranted.
-
-Teams are allowed to define their own rules about membership.
-
-For example, some teams will represent a business or other group which
-wants to carefully track its members. Other teams may be very open about
-who can join, and allow anybody to participate.
-
-When reviewing changes to a team, read the team's scope and the context
-around the member list for indications about the team's membership
-policy.
-
-In any case, request reviews from the existing team members. If the team
-lists no specific membership policy, feel free to merge changes to the
-team after giving the existing members a few days to respond.
-
-*Important:* If a team says it is a closed group, do not merge additions
-to the team without an approval by at least one existing member.
-
-## Other submissions {#reviewing-contributions-other-submissions}
-
-Other type of submissions requires different reviewing steps.
-
-If you consider having enough knowledge and experience in a topic and would like to be a long-term reviewer for related submissions, please contact the current reviewers for that topic. They will give you information about the reviewing process. The main reviewers for a topic can be hard to find as there is no list, but checking past pull requests to see who reviewed or git-blaming the code to see who committed to that topic can give some hints.
-
-Container system, boot system and library changes are some examples of the pull requests fitting this category.
-
-## Merging pull requests {#reviewing-contributions--merging-pull-requests}
-
-It is possible for community members that have enough knowledge and experience on a special topic to contribute by merging pull requests.
-
-In case the PR is stuck waiting for the original author to apply a trivial
-change (a typo, capitalisation change, etc.) and the author allowed the members
-to modify the PR, consider applying it yourself. (or commit the existing review
-suggestion) You should pay extra attention to make sure the addition doesn't go
-against the idea of the original PR and would not be opposed by the author.
-
-<!--
-The following paragraphs about how to deal with unactive contributors is just a proposition and should be modified to what the community agrees to be the right policy.
-
-Please note that contributors with commit rights unactive for more than three months will have their commit rights revoked.
--->
-
-Please see the discussion in [GitHub nixpkgs issue #50105](https://github.com/NixOS/nixpkgs/issues/50105) for information on how to proceed to be granted this level of access.
-
-In a case a contributor definitively leaves the Nix community, they should create an issue or post on [Discourse](https://discourse.nixos.org) with references of packages and modules they maintain so the maintainership can be taken over by other contributors.

-
-## Making patches {#submitting-changes-making-patches}
-
-- Read [Manual (How to write packages for Nix)](https://nixos.org/nixpkgs/manual/).
-
-- Fork [the Nixpkgs repository](https://github.com/nixos/nixpkgs/) on GitHub.
-
-- Create a branch for your future fix.
-
-  - You can make branch from a commit of your local `nixos-version`. That will help you to avoid additional local compilations. Because you will receive packages from binary cache. For example
-
-    ```ShellSession
-    $ nixos-version --hash
-    0998212
-    $ git checkout 0998212
-    $ git checkout -b 'fix/pkg-name-update'
-    ```
-
-  - Please avoid working directly on the `master` branch.
-
-- Make commits of logical units.
-
-- If you removed pkgs or made some major NixOS changes, write about it in the release notes for the next stable release. For example `nixos/doc/manual/release-notes/rl-2003.xml`.
-
-- Check for unnecessary whitespace with `git diff --check` before committing.
-
-- Format the commit in a following way:
-
-  ```
-  (pkg-name | nixos/<module>): (from -> to | init at version | refactor | etc)
-  Additional information.
-  ```
-
-  - Examples:
-    - `nginx: init at 2.0.1`
-    - `firefox: 54.0.1 -> 55.0`
-    - `nixos/hydra: add bazBaz option`
-    - `nixos/nginx: refactor config generation`
-
-- Test your changes. If you work with
-
-  - nixpkgs:
-
-    - update pkg
-      - `nix-env -iA pkg-attribute-name -f <path to your local nixpkgs folder>`
-    - add pkg
-      - Make sure it’s in `pkgs/top-level/all-packages.nix`
-      - `nix-env -iA pkg-attribute-name -f <path to your local nixpkgs folder>`
-    - _If you don’t want to install pkg in you profile_.
-      - `nix-build -A pkg-attribute-name <path to your local nixpkgs folder>` and check results in the folder `result`. It will appear in the same directory where you did `nix-build`.
-    - If you installed your package with `nix-env`, you can run `nix-env -e pkg-name` where `pkg-name` is as reported by `nix-env -q` to uninstall it from your system.
-
-  - NixOS and its modules:
-    - You can add new module to your NixOS configuration file (usually it’s `/etc/nixos/configuration.nix`). And do `sudo nixos-rebuild test -I nixpkgs=<path to your local nixpkgs folder> --fast`.
-
-- If you have commits `pkg-name: oh, forgot to insert whitespace`: squash commits in this case. Use `git rebase -i`.
-
-- [Rebase](https://git-scm.com/book/en/v2/Git-Branching-Rebasing) your branch against current `master`.
-
-## Submitting changes {#submitting-changes-submitting-changes}
-
-- Push your changes to your fork of nixpkgs.
-- Create the pull request
-- Follow [the contribution guidelines](https://github.com/NixOS/nixpkgs/blob/master/CONTRIBUTING.md#submitting-changes).
-
-## Submitting security fixes {#submitting-changes-submitting-security-fixes}
-
-Security fixes are submitted in the same way as other changes and thus the same guidelines apply.
-
-- If a new version fixing the vulnerability has been released, update the package;
-- If the security fix comes in the form of a patch and a CVE is available, then add the patch to the Nixpkgs tree, and apply it to the package.
-  The name of the patch should be the CVE identifier, so e.g. `CVE-2019-13636.patch`; If a patch is fetched the name needs to be set as well, e.g.:
-
-  ```nix
-  (fetchpatch {
-    name = "CVE-2019-11068.patch";
-    url = "https://gitlab.gnome.org/GNOME/libxslt/commit/e03553605b45c88f0b4b2980adfbbb8f6fca2fd6.patch";
-    hash = "sha256-SEKe/8HcW0UBHCfPTTOnpRlzmV2nQPPeL6HOMxBZd14=";
-  })
-  ```
-
-If a security fix applies to both master and a stable release then, similar to regular changes, they are preferably delivered via master first and cherry-picked to the release branch.
-
-Critical security fixes may by-pass the staging branches and be delivered directly to release branches such as `master` and `release-*`.
-
-## Deprecating/removing packages {#submitting-changes-deprecating-packages}
-
-There is currently no policy when to remove a package.
-
-Before removing a package, one should try to find a new maintainer or fix smaller issues first.
-
-### Steps to remove a package from Nixpkgs {#steps-to-remove-a-package-from-nixpkgs}
-
-We use jbidwatcher as an example for a discontinued project here.
-
-1. Have Nixpkgs checked out locally and up to date.
-1. Create a new branch for your change, e.g. `git checkout -b jbidwatcher`
-1. Remove the actual package including its directory, e.g. `git rm -rf pkgs/applications/misc/jbidwatcher`
-1. Remove the package from the list of all packages (`pkgs/top-level/all-packages.nix`).
-1. Add an alias for the package name in `pkgs/top-level/aliases.nix` (There is also `pkgs/applications/editors/vim/plugins/aliases.nix`. Package sets typically do not have aliases, so we can't add them there.)
-
-    For example in this case:
-
-    ```
-    jbidwatcher = throw "jbidwatcher was discontinued in march 2021"; # added 2021-03-15
-    ```
-
-    The throw message should explain in short why the package was removed for users that still have it installed.
-
-1. Test if the changes introduced any issues by running `nix-env -qaP -f . --show-trace`. It should show the list of packages without errors.
-1. Commit the changes. Explain again why the package was removed. If it was declared discontinued upstream, add a link to the source.
-
-    ```ShellSession
-    $ git add pkgs/applications/misc/jbidwatcher/default.nix pkgs/top-level/all-packages.nix pkgs/top-level/aliases.nix
-    $ git commit
-    ```
-
-    Example commit message:
-
-    ```
-    jbidwatcher: remove
-
-    project was discontinued in march 2021. the program does not work anymore because ebay changed the login.
-
-    https://web.archive.org/web/20210315205723/http://www.jbidwatcher.com/
-    ```
-
-1. Push changes to your GitHub fork with `git push`
-1. Create a pull request against Nixpkgs. Mention the package maintainer.
-
-This is how the pull request looks like in this case: [https://github.com/NixOS/nixpkgs/pull/116470](https://github.com/NixOS/nixpkgs/pull/116470)
-
-## Pull Request Template {#submitting-changes-pull-request-template}
-
-The pull request template helps determine what steps have been made for a contribution so far, and will help guide maintainers on the status of a change. The motivation section of the PR should include any extra details the title does not address and link any existing issues related to the pull request.
-
-When a PR is created, it will be pre-populated with some checkboxes detailed below:
-
-### Tested using sandboxing {#submitting-changes-tested-with-sandbox}
-
-When sandbox builds are enabled, Nix will setup an isolated environment for each build process. It is used to remove further hidden dependencies set by the build environment to improve reproducibility. This includes access to the network during the build outside of `fetch*` functions and files outside the Nix store. Depending on the operating system access to other resources are blocked as well (ex. inter process communication is isolated on Linux); see [sandbox](https://nixos.org/nix/manual/#conf-sandbox) in Nix manual for details.
-
-Sandboxing is not enabled by default in Nix due to a small performance hit on each build. In pull requests for [nixpkgs](https://github.com/NixOS/nixpkgs/) people are asked to test builds with sandboxing enabled (see `Tested using sandboxing` in the pull request template) because in<https://nixos.org/hydra/> sandboxing is also used.
-
-Depending if you use NixOS or other platforms you can use one of the following methods to enable sandboxing **before** building the package:
-
-- **Globally enable sandboxing on NixOS**: add the following to `configuration.nix`
-
-  ```nix
-  nix.useSandbox = true;
-  ```
-
-- **Globally enable sandboxing on non-NixOS platforms**: add the following to: `/etc/nix/nix.conf`
-
-  ```ini
-  sandbox = true
-  ```
-
-### Built on platform(s) {#submitting-changes-platform-diversity}
-
-Many Nix packages are designed to run on multiple platforms. As such, it’s important to let the maintainer know which platforms your changes have been tested on. It’s not always practical to test a change on all platforms, and is not required for a pull request to be merged. Only check the systems you tested the build on in this section.
-
-### Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests) {#submitting-changes-nixos-tests}
-
-Packages with automated tests are much more likely to be merged in a timely fashion because it doesn’t require as much manual testing by the maintainer to verify the functionality of the package. If there are existing tests for the package, they should be run to verify your changes do not break the tests. Tests can only be run on Linux. For more details on writing and running tests, see the [section in the NixOS manual](https://nixos.org/nixos/manual/index.html#sec-nixos-tests).
-
-### Tested compilation of all pkgs that depend on this change using `nixpkgs-review` {#submitting-changes-tested-compilation}
-
-If you are updating a package’s version, you can use `nixpkgs-review` to make sure all packages that depend on the updated package still compile correctly. The `nixpkgs-review` utility can look for and build all dependencies either based on uncommitted changes with the `wip` option or specifying a GitHub pull request number.
-
-Review changes from pull request number 12345:
-
-```ShellSession
-nix-shell -p nixpkgs-review --run "nixpkgs-review pr 12345"
-```
-
-Alternatively, with flakes (and analogously for the other commands below):
-
-```ShellSession
-nix run nixpkgs#nixpkgs-review -- pr 12345
-```
-
-Review uncommitted changes:
-
-```ShellSession
-nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
-```
-
-Review changes from last commit:
-
-```ShellSession
-nix-shell -p nixpkgs-review --run "nixpkgs-review rev HEAD"
-```
-
-### Tested execution of all binary files (usually in `./result/bin/`) {#submitting-changes-tested-execution}
-
-It’s important to test any executables generated by a build when you change or create a package in nixpkgs. This can be done by looking in `./result/bin` and running any files in there, or at a minimum, the main executable for the package. For example, if you make a change to texlive, you probably would only check the binaries associated with the change you made rather than testing all of them.
-
-### Meets Nixpkgs contribution standards {#submitting-changes-contribution-standards}
-
-The last checkbox is fits [CONTRIBUTING.md](https://github.com/NixOS/nixpkgs/blob/master/CONTRIBUTING.md). The contributing document has detailed information on standards the Nix community has for commit messages, reviews, licensing of contributions you make to the project, etc... Everyone should read and understand the standards the community has for contributing before submitting a pull request.
-
-## Hotfixing pull requests {#submitting-changes-hotfixing-pull-requests}
-
-- Make the appropriate changes in you branch.
-- Don’t create additional commits, do
-  - `git rebase -i`
-  - `git push --force` to your branch.
-
-## Commit policy {#submitting-changes-commit-policy}
-
-- Commits must be sufficiently tested before being merged, both for the master and staging branches.
-- Hydra builds for master and staging should not be used as testing platform, it’s a build farm for changes that have been already tested.
-- When changing the bootloader installation process, extra care must be taken. Grub installations cannot be rolled back, hence changes may break people’s installations forever. For any non-trivial change to the bootloader please file a PR asking for review, especially from \@edolstra.
-
-### Branches {#submitting-changes-branches}
-
-The `nixpkgs` repository has three major branches:
-- `master`
-- `staging`
-- `staging-next`
-
-The most important distinction between them is that `staging`
-(colored red in the diagram below) can receive commits which cause
-a mass-rebuild (for example, anything that changes the `drvPath` of
-`stdenv`).  The other two branches `staging-next` and `master`
-(colored green in the diagram below) can *not* receive commits which
-cause a mass-rebuild.
-
-Arcs between the branches show possible merges into these branches,
-either from other branches or from independently submitted PRs.  The
-colors of these edges likewise show whether or not they could
-trigger a mass rebuild (red) or must not trigger a mass rebuild
-(green).
-
-Hydra runs automatic builds for the green branches.
-
-Notice that the automatic merges are all green arrows.  This is by
-design.  Any merge which might cause a mass rebuild on a branch
-which has automatic builds (`staging-next`, `master`) will be a
-manual merge to make sure it is good use of compute power.
-
-Nixpkgs has two branches so that there is one branch (`staging`)
-which accepts mass-rebuilding commits, and one fast-rebuilding
-branch which accepts independent PRs (`master`).  The `staging-next`
-branch allows the Hydra operators to batch groups of commits to
-`staging` to be built.  By keeping the `staging-next` branch
-separate from `staging`, this batching does not block
-developers from merging changes into `staging`.
-
-```{.graphviz caption="Staging workflow"}
-digraph {
-    master [color="green" fontcolor=green]
-    "staging-next" [color="green" fontcolor=green]
-    staging [color="red" fontcolor=red]
-
-    "small changes" [fontcolor=green shape=none]
-    "small changes" -> master [color=green]
-
-    "mass-rebuilds and other large changes" [fontcolor=red shape=none]
-    "mass-rebuilds and other large changes" -> staging [color=red]
-
-    "critical security fixes" [fontcolor=green shape=none]
-    "critical security fixes" -> master [color=green]
-
-    "staging fixes which do not cause staging to mass-rebuild" [fontcolor=green shape=none]
-    "staging fixes which do not cause staging to mass-rebuild" -> "staging-next" [color=green]
-
-    "staging-next" -> master [color="red"] [label="manual merge"] [fontcolor="red"]
-    "staging" -> "staging-next" [color="red"] [label="manual merge"] [fontcolor="red"]
-
-    master -> "staging-next" [color="green"] [label="automatic merge (GitHub Action)"] [fontcolor="green"]
-    "staging-next" -> staging [color="green"] [label="automatic merge (GitHub Action)"] [fontcolor="green"]
-}
-```
-
-[This GitHub Action](https://github.com/NixOS/nixpkgs/blob/master/.github/workflows/periodic-merge-6h.yml) brings changes from `master` to `staging-next` and from `staging-next` to `staging` every 6 hours; these are the green arrows in the diagram above.  The red arrows in the diagram above are done manually and much less frequently.  You can get an idea of how often these merges occur by looking at the git history.
-
-
-#### Master branch {#submitting-changes-master-branch}
-
-The `master` branch is the main development branch. It should only see non-breaking commits that do not cause mass rebuilds.
-
-#### Staging branch {#submitting-changes-staging-branch}
-
-The `staging` branch is a development branch where mass-rebuilds go. Mass rebuilds are commits that cause rebuilds for many packages, like more than 500 (or perhaps, if it's 'light' packages, 1000). It should only see non-breaking mass-rebuild commits. That means it is not to be used for testing, and changes must have been well tested already. If the branch is already in a broken state, please refrain from adding extra new breakages.
-
-During the process of a releasing a new NixOS version, this branch or the release-critical packages can be restricted to non-breaking changes.
-
-#### Staging-next branch {#submitting-changes-staging-next-branch}
-
-The `staging-next` branch is for stabilizing mass-rebuilds submitted to the `staging` branch prior to merging them into `master`. Mass-rebuilds must go via the `staging` branch. It must only see non-breaking commits that are fixing issues blocking it from being merged into the `master` branch.
-
-If the branch is already in a broken state, please refrain from adding extra new breakages. Stabilize it for a few days and then merge into master.
-
-During the process of a releasing a new NixOS version, this branch or the release-critical packages can be restricted to non-breaking changes.
-
-#### Stable release branches {#submitting-changes-stable-release-branches}
-
-The same staging workflow applies to stable release branches, but the main branch is called `release-*` instead of `master`.
-
-Example branch names: `release-21.11`, `staging-21.11`, `staging-next-21.11`.
-
-Most changes added to the stable release branches are cherry-picked (“backported”) from the `master` and staging branches.
-
-#### Automatically backporting a Pull Request {#submitting-changes-stable-release-branches-automatic-backports}
-
-Assign label `backport <branch>` (e.g. `backport release-21.11`) to the PR and a backport PR is automatically created after the PR is merged.
-
-#### Manually backporting changes {#submitting-changes-stable-release-branches-manual-backports}
-
-Cherry-pick changes via `git cherry-pick -x <original commit>` so that the original commit id is included in the commit message.
-
-Add a reason for the backport when it is not obvious from the original commit message. You can do this by cherry picking with `git cherry-pick -xe <original commit>`, which allows editing the commit message. This is not needed for minor version updates that include security and bug fixes but don't add new features or when the commit fixes an otherwise broken package.
-
-Here is an example of a cherry-picked commit message with good reason description:
-
-```
-zfs: Keep trying root import until it works
-
-Works around #11003.
-
-(cherry picked from commit 98b213a11041af39b39473906b595290e2a4e2f9)
-
-Reason: several people cannot boot with ZFS on NVMe
-```
-
-Other examples of reasons are:
-
-- Previously the build would fail due to, e.g., `getaddrinfo` not being defined
-- The previous download links were all broken
-- Crash when starting on some X11 systems
-
-#### Acceptable backport criteria {#acceptable-backport-criteria}
-
-The stable branch does have some changes which cannot be backported. Most notable are breaking changes. The desire is to have stable users be uninterrupted when updating packages.
-
-However, many changes are able to be backported, including:
-- New Packages / Modules
-- Security / Patch updates
-- Version updates which include new functionality (but no breaking changes)
-- Services which require a client to be up-to-date regardless. (E.g. `spotify`, `steam`, or `discord`)
-- Security critical applications (E.g. `firefox`)

-# Vulnerability Roundup {#chap-vulnerability-roundup}
-
-## Issues {#vulnerability-roundup-issues}
-
-Vulnerable packages in Nixpkgs are managed using issues.
-Currently opened ones can be found using the following:
-
-[github.com/NixOS/nixpkgs/issues?q=is:issue+is:open+"Vulnerability+roundup"](https://github.com/NixOS/nixpkgs/issues?q=is%3Aissue+is%3Aopen+%22Vulnerability+roundup%22)
-
-Each issue correspond to a vulnerable version of a package; As a consequence:
-
-- One issue can contain several CVEs;
-- One CVE can be shared across several issues;
-- A single package can be concerned by several issues.
-
-
-A "Vulnerability roundup" issue usually respects the following format:
-
-```txt
-<link to relevant package search on search.nix.gsc.io>, <link to relevant files in Nixpkgs on GitHub>
-
-<list of related CVEs, their CVSS score, and the impacted NixOS version>
-
-<list of the scanned Nixpkgs versions>
-
-<list of relevant contributors>
-```
-
-Note that there can be an extra comment containing links to previously reported (and still open) issues for the same package.
-
-
-## Triaging and Fixing {#vulnerability-roundup-triaging-and-fixing}
-
-**Note**: An issue can be a "false positive" (i.e. automatically opened, but without the package it refers to being actually vulnerable).
-If you find such a "false positive", comment on the issue an explanation of why it falls into this category, linking as much information as the necessary to help maintainers double check.
-
-If you are investigating a "true positive":
-
-- Find the earliest patched version or a code patch in the CVE details;
-- Is the issue already patched (version up-to-date or patch applied manually) in Nixpkgs's `master` branch?
-  - **No**:
-    - [Submit a security fix](#submitting-changes-submitting-security-fixes);
-    - Once the fix is merged into `master`, [submit the change to the vulnerable release branch(es)](https://nixos.org/manual/nixpkgs/stable/#submitting-changes-stable-release-branches);
-  - **Yes**: [Backport the change to the vulnerable release branch(es)](https://nixos.org/manual/nixpkgs/stable/#submitting-changes-stable-release-branches).
-- When the patch has made it into all the relevant branches (`master`, and the vulnerable releases), close the relevant issue(s).

-# Debugging Nix Expressions {#sec-debug}
-
-Nix is a unityped, dynamic language, this means every value can potentially appear anywhere. Since it is also non-strict, evaluation order and what ultimately is evaluated might surprise you. Therefore it is important to be able to debug nix expressions.
-
-In the `lib/debug.nix` file you will find a number of functions that help (pretty-)printing values while evaluation is running. You can even specify how deep these values should be printed recursively, and transform them on the fly. Please consult the docstrings in `lib/debug.nix` for usage information.

-# Generators {#sec-generators}
-Generators are functions that create file formats from nix data structures, e. g. for configuration files. There are generators available for: `INI`, `JSON` and `YAML`
-
-All generators follow a similar call interface: `generatorName configFunctions data`, where `configFunctions` is an attrset of user-defined functions that format nested parts of the content. They each have common defaults, so often they do not need to be set manually. An example is `mkSectionName ? (name: libStr.escape [ "[" "]" ] name)` from the `INI` generator. It receives the name of a section and sanitizes it. The default `mkSectionName` escapes `[` and `]` with a backslash.
-
-Generators can be fine-tuned to produce exactly the file format required by your application/service. One example is an INI-file format which uses `: ` as separator, the strings `"yes"`/`"no"` as boolean values and requires all string values to be quoted:
-
-```nix
-with lib;
-let
-  customToINI = generators.toINI {
-    # specifies how to format a key/value pair
-    mkKeyValue = generators.mkKeyValueDefault {
-      # specifies the generated string for a subset of nix values
-      mkValueString = v:
-             if v == true then ''"yes"''
-        else if v == false then ''"no"''
-        else if isString v then ''"${v}"''
-        # and delegates all other values to the default generator
-        else generators.mkValueStringDefault {} v;
-    } ":";
-  };
-
-# the INI file can now be given as plain old nix values
-in customToINI {
-  main = {
-    pushinfo = true;
-    autopush = false;
-    host = "localhost";
-    port = 42;
-  };
-  mergetool = {
-    merge = "diff3";
-  };
-}
-```
-
-This will produce the following INI file as nix string:
-
-```INI
-[main]
-autopush:"no"
-host:"localhost"
-port:42
-pushinfo:"yes"
-str\:ange:"very::strange"
-
-[mergetool]
-merge:"diff3"

-# pkgs.nix-gitignore {#sec-pkgs-nix-gitignore}
-
-`pkgs.nix-gitignore` is a function that acts similarly to `builtins.filterSource` but also allows filtering with the help of the gitignore format.
-
-## Usage {#sec-pkgs-nix-gitignore-usage}
-
-`pkgs.nix-gitignore` exports a number of functions, but you'll most likely need either `gitignoreSource` or `gitignoreSourcePure`. As their first argument, they both accept either 1. a file with gitignore lines or 2. a string with gitignore lines, or 3. a list of either of the two. They will be concatenated into a single big string.
-
-```nix
-{ pkgs ? import <nixpkgs> {} }:
-
- nix-gitignore.gitignoreSource [] ./source
-     # Simplest version
-
- nix-gitignore.gitignoreSource "supplemental-ignores\n" ./source
-     # This one reads the ./source/.gitignore and concats the auxiliary ignores
-
- nix-gitignore.gitignoreSourcePure "ignore-this\nignore-that\n" ./source
-     # Use this string as gitignore, don't read ./source/.gitignore.
-
- nix-gitignore.gitignoreSourcePure ["ignore-this\nignore-that\n", ~/.gitignore] ./source
-     # It also accepts a list (of strings and paths) that will be concatenated
-     # once the paths are turned to strings via readFile.
-```
-
-These functions are derived from the `Filter` functions by setting the first filter argument to `(_: _: true)`:
-
-```nix
-gitignoreSourcePure = gitignoreFilterSourcePure (_: _: true);
-gitignoreSource = gitignoreFilterSource (_: _: true);
-```
-
-Those filter functions accept the same arguments the `builtins.filterSource` function would pass to its filters, thus `fn: gitignoreFilterSourcePure fn ""` should be extensionally equivalent to `filterSource`. The file is blacklisted if it's blacklisted by either your filter or the gitignoreFilter.
-
-If you want to make your own filter from scratch, you may use
-
-```nix
-gitignoreFilter = ign: root: filterPattern (gitignoreToPatterns ign) root;
-```
-
-## gitignore files in subdirectories {#sec-pkgs-nix-gitignore-usage-recursive}
-
-If you wish to use a filter that would search for .gitignore files in subdirectories, just like git does by default, use this function:
-
-```nix
-gitignoreFilterRecursiveSource = filter: patterns: root:
-# OR
-gitignoreRecursiveSource = gitignoreFilterSourcePure (_: _: true);

-This is a special setup hook which helps in packaging proprietary software in that it automatically tries to find missing shared library dependencies of ELF files based on the given `buildInputs` and `nativeBuildInputs`.
-
-You can also specify a `runtimeDependencies` variable which lists dependencies to be unconditionally added to rpath of all executables. This is useful for programs that use dlopen 3 to load libraries at runtime.
-
-In certain situations you may want to run the main command (`autoPatchelf`) of the setup hook on a file or a set of directories instead of unconditionally patching all outputs. This can be done by setting the `dontAutoPatchelf` environment variable to a non-empty value.
-
-By default `autoPatchelf` will fail as soon as any ELF file requires a dependency which cannot be resolved via the given build inputs. In some situations you might prefer to just leave missing dependencies unpatched and continue to patch the rest. This can be achieved by setting the `autoPatchelfIgnoreMissingDeps` environment variable to a non-empty value. `autoPatchelfIgnoreMissingDeps` can be set to a list like `autoPatchelfIgnoreMissingDeps = [ "libcuda.so.1" "libcudart.so.1" ];` or to simply `[ "*" ]` to ignore all missing dependencies.

Installing cntr and running the command will provide shell access to the build sandbox of failed build. At `/var/lib/cntr` the sandboxed filesystem is mounted. All commands and files of the system are still accessible within the shell. To execute commands from the sandbox use the cntr exec subcommand. `cntr` is only supported on Linux-based platforms. To use it first add `cntr` to your `environment.systemPackages` on NixOS or alternatively to the root user on non-NixOS systems. Then in the package that is supposed to be inspected, add `breakpointHook` to `nativeBuildInputs`.
-
-```nix
-nativeBuildInputs = [ breakpointHook ];
-```
-
-When a build failure happens there will be an instruction printed that shows how to attach with `cntr` to the build sandbox.
-
-::: {.note}
-Caution with remote builds
-
-This won’t work with remote builds as the build environment is on a different machine and can’t be accessed by `cntr`. Remote builds can be turned off by setting `--option builders ''` for `nix-build` or `--builders ''` for `nix build`.

-Overrides the default configure phase to run the CMake command. By default, we use the Make generator of CMake. In addition, dependencies are added automatically to `CMAKE_PREFIX_PATH` so that packages are correctly detected by CMake. Some additional flags are passed in to give similar behavior to configure-based packages. You can disable this hook’s behavior by setting `configurePhase` to a custom value, or by setting `dontUseCmakeConfigure`. `cmakeFlags` controls flags passed only to CMake. By default, parallel building is enabled as CMake supports parallel building almost everywhere. When Ninja is also in use, CMake will detect that and use the ninja generator.

-# `installShellFiles` {#installshellfiles}
-
-This hook helps with installing manpages and shell completion files. It exposes 2 shell functions `installManPage` and `installShellCompletion` that can be used from your `postInstall` hook.
-
-The `installManPage` function takes one or more paths to manpages to install. The manpages must have a section suffix, and may optionally be compressed (with `.gz` suffix). This function will place them into the correct directory.
-
-The `installShellCompletion` function takes one or more paths to shell completion files. By default it will autodetect the shell type from the completion file extension, but you may also specify it by passing one of `--bash`, `--fish`, or `--zsh`. These flags apply to all paths listed after them (up until another shell flag is given). Each path may also have a custom installation name provided by providing a flag `--name NAME` before the path. If this flag is not provided, zsh completions will be renamed automatically such that `foobar.zsh` becomes `_foobar`. A root name may be provided for all paths using the flag `--cmd NAME`; this synthesizes the appropriate name depending on the shell (e.g. `--cmd foo` will synthesize the name `foo.bash` for bash and `_foo` for zsh). The path may also be a fifo or named fd (such as produced by `<(cmd)`), in which case the shell and name must be provided.

-# `patchRcPath` hooks {#sec-patchRcPathHooks}
-
-These hooks provide shell-specific utilities (with the same name as the hook) to patch shell scripts meant to be sourced by software users.
-
-The typical usage is to patch initialisation or [rc](https://unix.stackexchange.com/questions/3467/what-does-rc-in-bashrc-stand-for) scripts inside `$out/bin` or `$out/etc`.
-Such scripts, when being sourced, would insert the binary locations of certain commands into `PATH`, modify other environment variables or run a series of start-up commands.
-When shipped from the upstream, they sometimes use commands that might not be available in the environment they are getting sourced in.
-
-The compatible shells for each hook are:
-
- - `patchRcPathBash`: [Bash](https://www.gnu.org/software/bash/), [ksh](http://www.kornshell.org/), [zsh](https://www.zsh.org/) and other shells supporting the Bash-like parameter expansions.
- - `patchRcPathCsh`: Csh scripts, such as those targeting [tcsh](https://www.tcsh.org/).
- - `patchRcPathFish`: [Fish](https://fishshell.com/) scripts.
- - `patchRcPathPosix`: POSIX-conformant shells supporting the limited parameter expansions specified by the POSIX standard. Current implementation uses the parameter expansion `${foo-}` only.
-
-For each supported shell, it modifies the script with a `PATH` prefix that is later removed when the script ends.
-It allows nested patching, which guarantees that a patched script may source another patched script.
-
-Syntax to apply the utility to a script:
-
-```sh
-patchRcPath<shell> <file> <PATH-prefix>
-```
-
-Example usage:
-
-Given a package `foo` containing an init script `this-foo.fish` that depends on `coreutils`, `man` and `which`,
-patch the init script for users to source without having the above dependencies in their `PATH`:
-
-```nix
-{ lib, stdenv, patchRcPathFish}:
-stdenv.mkDerivation {
-
-  # ...
-
-  nativeBuildInputs = [
-    patchRcPathFish
-  ];
-
-  postFixup = ''
-    patchRcPathFish $out/bin/this-foo.fish ${lib.makeBinPath [ coreutils man which ]}
-  '';
-}
-```
-
-::: {.note}
-`patchRcPathCsh` and `patchRcPathPosix` implementation depends on `sed` to do the string processing.
-The others are in vanilla shell and have no third-party dependencies.

- - `PGDATA`: location of server files.
- - `PGHOST`: location of UNIX domain socket directory; the default `host` in a connection string.
- - `PGUSER`: user to create / log in with, default: `test_user`.
- - `PGDATABASE`: database name, default: `test_db`.
-
-Bash-only variables:
-
- - `postgresqlTestUserOptions`: SQL options to use when creating the `$PGUSER` role, default: `"LOGIN"`. Example: `"LOGIN SUPERUSER"`
- - `postgresqlTestSetupSQL`: SQL commands to run as database administrator after startup, default: statements that create `$PGUSER` and `$PGDATABASE`.
- - `postgresqlTestSetupCommands`: bash commands to run after database start, defaults to running `$postgresqlTestSetupSQL` as database administrator.
- - `postgresqlEnableTCP`: set to `1` to enable TCP listening. Flaky; not recommended.

-## Hooks {#sec-postgresqlTestHook-hooks}

-A number of additional hooks are ran in postgresqlTestHook
-
- - `postgresqlTestSetupPost`: ran after postgresql has been set up.
-
-## TCP and the Nix sandbox {#sec-postgresqlTestHook-tcp}
-
-`postgresqlEnableTCP` relies on network sandboxing, which is not available on macOS and some custom Nix installations, resulting in flaky tests.
-For this reason, it is disabled by default.
-
-The preferred solution is to make the test suite use a UNIX domain socket connection. This is the default behavior when no `host` connection parameter is provided.
-Some test suites hardcode a value for `host` though, so a patch may be required. If you can upstream the patch, you can make `host` default to the `PGHOST` environment variable when set. Otherwise, you can patch it locally to omit the `host` connection string parameter altogether.
-
-::: {.note}
-The error `libpq: failed (could not receive data from server: Connection refused` is generally an indication that the test suite is trying to connect through TCP.
