[Bug 1959054] Re: debhelper restarts services marked --no-restart-on-upgrade

Ah, very useful. sarnold has kindly run a similar search on all
components of the Ubuntu archive for jammy. I'm currently going through
this, and comparing it to a similar run on codesearch.debian.net
(incidentally, this issue affects both dh_installsystemd *and*
dh_installinit usage). I'll post a full list of affected packages to
this ticket, and the upstream Debian ticket once I've weeded it out
(there's a few false positives in there with changelog entries,
commented out bits, etc.)

Bug description:
  Debian bug #994204 (https://bugs.debian.org/cgi-
  bin/bugreport.cgi?bug=994204) describes a flaw in debhelper that
  results in the postinst being generated in such a fashion that
  services marked --no-stop-on-upgrade (or its deprecated alias --no-
  restart-on-upgrade), restart anyway.

  Please note: this is nothing to do with the --no-restart-after-upgrade
  flag (which is, somewhat confusingly IMO, unrelated).

  I've confirmed that the flaw appears to be present in the jammy
  version of debhelper (though not impish) and that packages generated
  with it appear to contain the flawed postinst (I first encountered
  this whilst working on the open-iscsi merge), though I haven't yet
  managed to test that the flaw exhibits itself on upgrade (though I'd
  say from the presence of the flaw in the postinst, that it's a
  reasonable inference that it will).

  In dbus (the merge of which I'm currently working on), Debian has
  worked around this but given I've now run into two affected packages
  (open-iscsi and dbus), only one of which has a work-around, I'd much
  rather we got debhelper fixed up and rebuilt affected packages?
