suggestion: rescue boot extension

[Alexander Boström]

Ok, a mini-Fedora that lives entirely in a subdir of the boot partition,
containing an application for managing grub.conf and other things.
Things it should be able to do:

      * Manage those yum-integrated btrfs snapshots.
      * Download Fedora and other distro pxeboot and live images and
        stick them in grub.conf.
      * Change default boot menu entry, edit entries etc.

Plus a terminal and various tools.
