This is like implementing grub in qemu (or pygrub in Xen). The level of
security exposure this introduces is really scary.
Oh that's really the wrong way to see it. We don't have bios, and
therefore we need _some_ functionality to start up initial code on the
disk. The interface that Alex is implementing is also used by the real
hardware to load from disk in case a scsi/fcp volume is used, and it is
part of the published machine architecture. That's very unlike grub.
