Descriptive yes, reliable no (IMO :)
UUIDs should always be more reliable so long as the "UU" part of their
name holds true :)
No reason you couldn't have both thought.

Hmm I did..
[midget 11:13] ~ >sudo gpart modify -i 2 -l "Midget-ZFS-1" ad4
ad4p2 modified
[midget 11:15] ~ >sudo gpart show -l ad4
=> 34 1953525101 ad4 GPT (932G)
34 8388608 1 (null) (4.0G)
8388642 1944059904 2 Midget-ZFS-1 (927G)
1952448546 1076589 - free - (526M)
but I get no /dev/gpt directory..
[midget 11:14] ~ >ls -la /dev/gpt
ls: /dev/gpt: No such file or directory
Maybe the UUID label got their first so it won't have an alias (although
the UUID is an alias for /dev/ad4p2..)
