It's done there and it works good.

In case of hardware failure, the chances that hd1 is renumbered in hd0
are rather high (either because faulty hd0 was removed, it didn't answer
the bios which dunked it, or you just changed bios boot order manually)

If you have / on lvm and your small /boot partition raid-1 mirrored on
every disk you use, suddenly you can plug your disks in any random
number and things will just work (linux-side that is).

Very magical, considering that other OS will fail at the slightest
change (and there grub remapping tricks may help)
