# Execute with
# nix-build -A nixosTests.nixpkgs-config-allow-unfree-packages-and-predicate --show-trace
#
# This test exercises the interaction between:
#
# - nixos/modules/misc/nixpkgs.nix (config merging, esp. allowUnfreePackages)
# - pkgs/stdenv/generic/check-meta.nix (allowUnfreePredicate logic)
#
# It checks how:
#
# * config.allowUnfreePackages
# * config.allowUnfreePredicate
#
# interact to determine whether unfree packages are allowed.
