[Bug 1681470] Re: libvirt-daemon-system package post scriptlet of Ubuntu-Cloud Occata for Xenial breaks /etc/group

[Dimitri John Ledkov]

Adding cloud-archive task, as I believe this is an integration issue
with the cloud-archive backport of libvirt; rather than just a straight
up Ubuntu release.

  ---Problem Description---
  Post installation scriptlet of package libvirt-daemon-system renders /etc/group database inconsistent, the identical group id is assigned to two different names
   
  Machine Type = IBM zSeries 2827 (EC12) 
   
  ---Steps to Reproduce---
   The addressed package is part of the Ubuntu-Cloud update repository for Occata on xenial:

  APT-Sources: http://ubuntu-cloud.archive.canonical.com/ubuntu xenial-
  updates/ocata/main s390x Packages

  In case version 1.3.3 of libvirt-daemon-system was installed on the
  system and you install version 2.5.0 from the Occata-Repository over
  it, the Post-Installation scriptlet will create a setup like this in
  /etc/group

  root at compzfw1:~# getent group | grep :121:
  libvirtd:x:121:
  libvirt:x:121:ubuntu,nova

  This is not a valid configuration, for example IBM internal tools detect those setups and mark the corresponding server "non-compliant".
  The post-scriptlet in question looks like this:

  [...]
  add_users_groups()
  {
      if ! getent group libvirt >/dev/null; then
          if getent group libvirtd >/dev/null; then
              gid=`getent group libvirtd | getent group libvirtd  | cut -d: -f3`
              groupadd --system --non-unique --gid "$gid" libvirt
  [...]

  If a new group with an existing GID is added, the group which previously was assigned to that GID must be consequently remove beforehand!
