Interestingly, the situation is different here (openSUSE):
root is only in group root, and nobody is in the groups
nobody and nogroup.
However, I've added some users which seem to be typical
for being member of one or more groups.

  for u in root man postfix sshd nobody ; do
    id $u >/dev/null 2>&1 && users="$users $u"
  done

New patch attached.  Thanks!

Have a nice day,
