Yo list!

  I just encountered something I think w/c is not right, e.g.:

 The previous action of deleting an invalid group (bleh) passed on to
-g via pw results in the 'wheel' group being deleted outright,
silently. Ouch.
 As an avid user of 'pw' I keep on inter-changing the -n and -g
switches (when working w/ pw user{add/mod/del} and pw
group{add/mod/del}), so it struck me when i realized I issued the
command above and the jail didnt know the 'wheel' group anymore when i
went on to do some other stuff (was installing ports when it didn't
know who's 'wheel', heh ;-)

 This happens on 5.4R and 6.0R, on my boxens.

 Thanks and FYI!


cheers
