Bug description:
  when I am trying to purge glance-comon I am receiving and error.
  The question about this issue is at:

  Output of:

       7 if (which deluser && getent passwd glance) > /dev/null 2>&1; then
       8 deluser --system --quiet --backup-to /var/lib glance
       9 fi
      10 if (which delgroup && getent group glance) > /dev/null 2>&1; then
      11 delgroup --system --quiet glance
      12 fi

  + getent passwd glance
  glance:x:64062:64062::/var/lib/glance:/bin/false
  + getent group glance
  glance:x:64062:
  + set +x

  Shows that the glance user and group id are not system(ie under 1000).
  Due to this the deluser and delgroup with the "--system" fails.

  I don't know if the UID and GID are wrong or if the "--system" flag is wrong.
  Either way it need to be fixed.

  Thanks,
