      The brightnessctl module was removed because newer versions of
      brightnessctl don't require the udev rules anymore (they can use the
      systemd-logind API). Instead of using the module you can now
      simply add the brightnessctl package to environment.systemPackages.

      The U2F modules module was removed, as all it did was adding the
