Code review comment for ~paelzer/ubuntu/+source/strongswan:merge-5.8.2-focal

Approved for landing the merge, a couple notes below.

* Changelog:
  - [√] old content and logical tag match as expected
  - [√] changelog entry correct version and targeted codename
  - [√] changelog entries correct
  - [√] update-maintainer has been run

* Actual changes:
  - [√] no upstream changes to consider
    + Debian is at 5.8.2-1 in unstable and unstable-debug
  - [-] no further upstream version to consider
  - [√] debian changes look safe

* Old Delta:
  - [-] dropped changes are ok to be dropped
  - [√] nothing else to drop
  - [√] changes forwarded upstream/debian (if appropriate)

* New Delta:
  - [√] no new patches added
  - [-] patches match what was proposed upstream
  - [-] patches correctly included in debian/patches/series
  - [-] patches have correct DEP3 metadata

* Build/Test:
  - [√] build is ok
  - [√] verified PPA package installs/uninstalls
  - [√] autopkgtest against the PPA package passes
  - [√] sanity checks test fine
    + systemd service had a warning (see below), but still PASS so maybe that was expected?

Can you provide an explanation in a comment the bug report, LP: #1861975, as to what the next steps will be? I.e. is libiptc's addition temporary until there is a better fix, or...? It's not critical this is done, and it certainly shouldn't delay the merge, but mainly I just want to make sure it's clear for future maintainers what they'd need to do going forward.

I verified the build was ok in the PPA. I tried git ubuntu build and debuild to run on this in my lxc checkout, but unsuccessfully unfortunately; I'm wondering if the dependency changes confused apt. I can give more details if you think this is worth exploring, but I'm ok trusting the PPA build, and my autopkgtest results.
