All proposed improvements are welcome. Just make sure that you have tested your changes before you submit new pull request.

Full test procedure:

* Generate clean MLL source tree with ``make src``. This will produce compressed archive file, e.g. ``minimal_linux_live_26-Dec-2017_src.tar.xz`` which contains all MLL sources.
* Copy or move the source archive file in empty folder and then extract the archive.
* Build MLL with ``./build_minimal_linux_live.sh``. You should be able to run MLL (``./qemu-bios.sh`` and/or ``./qemu-uefi.sh``) with the changes you have made.
* Repackage the MLL ISO image with ``./repackage.sh``. You should be able to run MLL (``./qemu-bios.sh`` and/or ``./qemu-uefi.sh``) with the changes you have made.
* Test the generated Docker functionality with ``test_docker_image.sh``. You should see message that the test has passed.
* Run shell console in Docker with ``./run_docker_console.sh``. You should be able to invoke all MLL binaries and scripts from this console.
