There's more to it than that. With PATA drives I see issues with order 
as well, and they date back to the Redhat 7.x days, where the install 
chose one order for the scsi drivers and the boot chose another. With 
IDE the order in which drivers are loaded affects the drive naming.

It would be great to have some way to match drives with names, but there 
doesn't seem to be a single solution for PATA, SATA, SCSI and hotplug. 
Something like mounts using UUID of the filesystem, but for the drives.

I do use pluggable drives for backup, load modules for various 
controllers on demand, etc, so I'm aware that the most reliable 
solutions seem to involve either reduced flexibility, human intervention 
at boot, or both.
