          Some systems require a /sbin/init script which is started.
          Or having it makes starting NixOS easier.
          This applies to some kind of hosting services and user mode linux.

          Additionally this script will create
          /boot/init-other-configurations-contents.txt containing
          contents of remaining configurations. You can copy paste them into
          /sbin/init manually running a rescue system or such.
        '';
      };
    };

  };


  ###### implementation

  config = mkIf config.boot.loader.initScript.enable {

    system.build.installBootLoader = initScriptBuilder;

  };

}
