FWIW, you can use the /dev/disk/by-*/* symlinks (as normally setup by 
udev) to reference various devices.

Of course because the identifiers behind by-uuid and by-label are per-
filesystem, those will normally only identify the one device of a multi-
device filesystem, but the by-id links ID on device serials and partition 
number, and if you are using GPT partitioning, you have by-partuuid and 
(if you set them when setting up the partitions) by-partlabel as well.
