Right. Subsequent reloads of gdm3.service should no longer kill
gdm3.service though. So this was indeed fixed in v222 but there seems to
be a specific issue for the upgrade path.
Once gdm3 has been restarted, a reload no longer causes it to be killed.

Indeed. I didn't run into this while testing. Sorry for that.
Bumping severity to RC, so other users are notified and the package
doesn't migrate to testing.

The issue seems to be reproducible and multiple users already reported
the same issue:
http://lists.alioth.debian.org/pipermail/pkg-systemd-maintainers/2015-July/008066.html
(CCed)

I suggest we follow up on this bug report.

I'm not yet quite sure, if this is a gdm or systemd bug and whether the
best course of action is to simply re-introduce the workaround patch and
drop that in stretch+1 or if we drop the reload from gdm3.postinst or if
this indeed another corner case which is not handled properly in systemd.
