        Additional packages to be included inside stage-1.

        Do note that *special manipulation* happens and may
        not be compatible with everything.

        The format for extra commands is:
        `{ package = _package_; extraCommand = _extraCommand_ }`

        Where extraCommand is executed at build time, generally
        to fix the package for stage-1 use.

        Commands ran particularly early for setting the framebuffer
        and framebuffer devices correctly.

        has been made available.
