The "boot=/dev/xxx" and "default=0" lines tell grub which kernel to
boot from which device, and it looks for the title with that
reference, 0-origin. Only if that boot fails does grub look elsewhere
for what to do. This is fairly well documented in 'info grub.'
The (far) more likely explanation is either that the md raid is messed
up or there are multiple possible boot partitions that do not match
what the machine sees and what the user is looking at.
