# This file adds the ability to whitelist unfree packages in different .nix config files.

# See https://github.com/NixOS/nixpkgs/issues/55674#issuecomment-1220216445 for why this is necessary.

# Example: Instead of
|
|
# nixpkgs.config.allowUnfreePredicate = pkg: builtins.elem (lib.getName pkg) [
|
|
# "obsidian"
|
|
# ];
|
|
# add the following
|
|
# allowUnfree = [ "obsidian" ];
