Easiest is to use labels. Old ide will keep hda,b,c,d constant
providing you have interfaces using the legacy IDE port mappings (0x1f0
and 0x170). Libata doesn't do that as pretty much every distribution had
already switched to volume labels, and the user space can do the job far
better than the kernel - especially as the newer devices with modern
interfaces don't have the old BIOS/DOS legacy ideas any more.
Mount by label also means you can flip back and forth between the
different drivers and kernel revisions.

It comes with one :)
# xfs_admin -u /dev/sdd2
UUID = 77ae4251-631f-4656-a365-c5723f5c5da8
Will try to use this to boot; however, I'd prefer the labels over the UUID,
wish there was an easy way to set it.

One final question, without udev, how does one determine the UUID of a non-XFS
partition, e.g., swap?
$ ls -l
