Hm, we're going to have to do this carefully. With the move to GPT partitions, both the UUID= designator in fstab and the /dev/disk/by -uuid/ of udev means the GPT UUID. In theory the design of the UUID space is to allow random selection without clashing, so we could just place the SCSI ones in here as well and perhaps there won't be a problem, but I'd like us to think about the consequences first.
