I would think that you could just use LABEL=, UUID=, or /dev/disk/by-uuid/foo. Those device names only work on the kernel boot line if you're using an initramfs, but I suspect that they'd work fine in fstab regardless. Situations like this of course are one of the reasons initramfs is so popular - they can be far smarter about finding the root filesystem. Disclaimer: I'm using an initramfs, so I can't vouch for what happens without one. Rich
