This is because the minimal profile has this line:

  environment.noXlibs = mkDefault true;

which in turn triggers:

   nixpkgs.config.packageOverrides = pkgs:
      { dbus = pkgs.dbus.override { useX11 = false; }; };

which means that anything depending on dbus needs to be rebuilt.

We probably could be smarter about this (e.g. by only rebuilding dbus.daemon
without X11).
