Attempting to run ufslabels.sh on a system using gmirror gives the following:

sed: 1: "s/mirror/gm0s1a/ufsid\/ ...": bad flag in substitute command: 'u'
FS: / on device mirror/gm0s1a with ufsid 46404044387e2bbf
FS: Swap on device mirror/gm0s1b
sed: 1: "s/mirror/gm0s1b/label\/ ...": bad flag in substitute command: 'l'

Commit changes? (y/n):

It might make sense to detect that it is a gmirror and to display a message accordingly vs spitting out errors.
At least if someone isn't paying attention, it doesn't appear to break things.. (though I didn't say yes to verify that)
