# Behaviors of these two NixOS modules would be different:
|
|
# { pkgs, ... }@inputs: { environment.systemPackages = [ pkgs.hello ]; }
|
|
# inputs: { environment.systemPackages = [ pkgs.hello ]; }
|
|
# The second one would failed to evaluate because nixpkgs would not pass pkgs to it.
|
|
# So that we wrote a wrapper to make it always works like the first one.
