Hi Lukasz,
if you create an new goup on an debian lenny system all is fine.
But Passwd::Unix does not create an etc/gshadow entry of this group. If
you try to remove this group with groupdel it works, but the following
message will appear:
groupdel: error removing shadow group entry
It would be nice, if Passwd::Unix also create the gshadow entry.
Thanks,
Jonas
