Public bug reported:
I've set up a raid1 on Gutsy server RC, I've go it set up so it works
using these instructions: http://advosys.ca/viewpoints/2007/04/setting-
up-software-raid-in-ubuntu-server/ (I've set up three raid1 partitions
/, /home and swap) The problem is if I test it by disconnecting one of
the drives Gutsy wont boot.
If I run the following commands

# /dev/md0
# /dev/md1
# /dev/md2

similar results for md1 and md2
However if I test it by unplugging a hard drive it wont boot
I've also tried creating a small non Raid /boot partition, but again if
I unplug a drive the system wont boot (grub starts fails to mount the
raid)
