Disc order changing isn't a problem -- software raid writes a superblock on
every partition and so it can detect if /dev/sdb suddenly becomes /dev/sda.
The real problem is telling which one is which to be able to pull and
replace.

Yes, this has been problematic for us.  To be honest, LILO seems to do a
better job than GRUB for software RAID, and even sometimes non-RAID
systems.  Something about the GRUB in CentOS 4 and newer hardware has been
very problematic.  Luckily, fixing it with lilo is real easy.

Except that I was also having problems getting PATA to boot on those
systems as well.
