Michael,
I'm not sure I understand. My Fedora fstab and grub.conf uses UUID's.
The UUID on the underlying raid devices is different to the filesystem
device. eg. /dev/md0 is RAID1 comprised of /dev/sd[a-d]1
/dev/md0: UUID="d046b3c4-8f1b-4c60-8982-9621cf2ac34c" SEC_TYPE="ext2"
TYPE="ext3" LABEL="BOOT"
/dev/sda1: UUID="bb2b88b1-b1a0-c8f7-2e40-e00de48ff896" TYPE="mdraid"
/dev/sdb1: UUID="bb2b88b1-b1a0-c8f7-2e40-e00de48ff896" TYPE="mdraid"
/dev/sdc1: UUID="bb2b88b1-b1a0-c8f7-2e40-e00de48ff896" TYPE="mdraid"
/dev/sdd1: UUID="bb2b88b1-b1a0-c8f7-2e40-e00de48ff896" TYPE="mdraid"
/etc/fstab:
UUID=d046b3c4-8f1b-4c60-8982-9621cf2ac34c /boot ext3 defaults 1 2
Regards
Clive
