Apparently, but only in single-user mode.  I think my problem is more
one of documentation.  The handbook is rather obtuse on the subject.
The inability to even locate or read the labels on a mounted system is
about as un-POLS as I've come across lately....

Thanks for the help, though.  I booted single-user, mounted a
usb-stick, and piped the output of geom label to a file on the stick.
Not fun.

Only having run FBSD for 4 years or so now, I wasn't aware of any good
sources for this kind of info except dmesg.  I'll be looking into
/var/log/messages more closely in the future.  You don't see it
mentioned too often in reference to noob questions.

Thanks,
Steve
