I am trying to change from using nixpkgs.config.allowUnfree = true to nixpkgs.config.allowUnfreePredicate, however I would like to keep all my unfree firmware. The problem is that hardware.enableAllFirmware is not compatible with that setup.
I tried switching to hardware.enableRedistributableFirmware to see what changed, however it just triggered a generic rebuild which according to my (admittedly limited) understanding of Nix doesn’t actually prove the contents were changed in a meaningful way.
these 8 derivations will be built:

How can I tell?
