       - The option definition `nix.gc.user' in `/nix/store/zkkcgy73xlq8p4vk46jrxs0rm02aq8zx-source/hosts/darwin' no longer has any effect; please remove it.
       The garbage collection service now always runs as `root`.

       - The option definition `services.nix-daemon.enable' in `/nix/store/zkkcgy73xlq8p4vk46jrxs0rm02aq8zx-source/hosts/darwin' no longer has any effect; please remove it.
       nix-darwin now manages nix-daemon unconditionally when
       `nix.enable` is on.
