The UUID is written on the disk when the partition is created. It's supposed to be a universally unique identifier for that partition. To the best of my knowledge, though, there's nothing to identify the disk itself. > It depends.

But you can control that, and once you figure the setting you like, it won't change. > But I don't have an udev configuration, not one I made myself.

Pretty well for all SCSIs or SATAs -- just be sure there's no USB stick plugged in. On my servers, I want to use a small fast SCSI system disk and a RAID of SATAs for data, and I want my system disk to repeatably be called /dev/sda.
