[Bug 1840347] Re: Ceph 12.2.12 restarts services during upgrade

[Eric Desrochers]

Hopefully that should do the trick:

override_dh_installinit:
.....
- # Ensure Debian/Ubuntu specific systemd units are NOT automatically enabled and started
- # Enable systemd targets only
- dh_systemd_enable -Xceph-mon.service -Xceph-osd.service -X ceph-mds.service
- # Start systemd targets only
- dh_systemd_start --no-restart-on-upgrade

override_dh_systemd_enable:
- # systemd start done as part of dh_installinit
+	dh_systemd_enable -Xceph-mon.service -Xceph-osd.service -X ceph-mds.service

override_dh_systemd_start:
- # systemd start done as part of dh_installinit
+	dh_systemd_start --no-stop-on-upgrade --no-restart-after-upgrade

Bug description:
  Upgrading from 12.2.11-0ubuntu0.18.04.2 to 12.2.12-0ubuntu0.18.04.1 on
  Ubuntu 18.04 causes the ceph-osd services to be restarted without
  prompting.

  This appears to be in the configure section on the ceph-common,postinst:
  # Automatically added by dh_systemd_start/11.1.6ubuntu2
  if [ "$1" = "configure" ] || [ "$1" = "abort-upgrade" ] || [ "$1" = "abort-deconfigure" ] || [ "$1" = "abort-remove" ] ; then
          if [ -d /run/systemd/system ]; then
                  systemctl --system daemon-reload >/dev/null || true
                  if [ -n "$2" ]; then
                          _dh_action=restart
                  else
                          _dh_action=start
                  fi
                  deb-systemd-invoke $_dh_action 'ceph.target' >/dev/null || true
          fi
  fi
  # End automatically added section

  dpkg.log after the upgrade shows that "configure" was exercised:
  2019-08-15 10:49:18 upgrade ceph-common:amd64 12.2.11-0ubuntu0.18.04.2 12.2.12-
  ...
  2019-08-15 10:49:29 configure ceph-common:amd64 12.2.12-0ubuntu0.18.04.1 <none>
  ..
  2019-08-15 10:49:56 status installed ceph-common:amd64 12.2.12-0ubuntu0.18.04.1
