Ah, ext3 labels are 16 bytes instead of 32. And I do agree using a full
UUID is hard to remember. So I'd still suggest using a smart label, e.g.
<release>-<mount-point>-<uuid>
and truncate appropriately. For example "F8t1-/boot-12345",
"F8-/-123456789ab" or whatever. That's both descriptive and will have a
relatively large UUID. Also, make sure to always use four digits of the
UUID, e.g. truncate the target mount point, e.g.
/some/filesystem/that/the/user/mounts/into/a/bizarre/and/long/mountpoint
if needed. Of course, it's a lot easier to just use the UUID :-)
