Comment 1 for bug 632775

00:51 <cjwatson> I think this is going to need something a bit like http://bazaar.launchpad.net/~vcs-imports/grub/grub2-bzr/revision/2465, only for EFI
00:52 <cjwatson> specifically the bit that handles a partition-only prefix "drive"
00:52 <cjwatson> the alternative is hardcoding the entire prefix device, which is seriously undesirable
00:53 <cjwatson> then the EFI grub-install will have to find the partition number for /boot/grub and hardcode that but make sure to leave out the drive
