The way I do it is setup identical boot partitions on both disks (not that
althout / is on a raid device, you still need a 'regular' partition to load
the kernel).
If the first disk fails you need to teach the bios/prom/whatever to boot from
the second one. unfortunably this need manual intervention but I've yet to find
a better way of doing it.
