Hi,

during a test with piuparts I noticed your package left unowned files on
the system after purge, which is a violation of policy 6.8 (or 10.8):

https://www.debian.org/doc/debian-policy/ch-maintainerscripts.html#s-removedetails

Filing this as important as having a piuparts clean archive is a release
goal since lenny.

0m34.0s ERROR: FAIL: Package purging left files on system:
  /etc/systemd/system/display-manager.service -> /lib/systemd/system/lightdm.service	 not owned

init-system-helpers which should be responsible for the cleanup is still
installed at purge time, so there sees to be something faulty with the
systemd integration in the packaging.
None of the other display managers has this problem.


cheers,

Andreas

Thanks for the report, I'll check what we do differently. As far as I
can tell, the symlink is manually created (in postinst), not by
init-system-helpers so it might explain it.

Regards,
