        # TODO:
        #  - come up with a 'parted' script that creates the partitions
        #    automatically
        #     - in particular, increase "repeatability", the ability
        #       to easily recreate the drive after it fails
        #  - add more boot options:
        #       - Hiren's
        #       - UBCD
        #       - Backtrack
        #       - bootloaders with autodiscovery
        #           - PLoP
        #           - Super GRUB2 Disk
        #           - Super GRUB Disk
