Comment 5 for bug 1505288

Hi Barry,
the stale missed removal of the conffile seems still around but I fail to see the installation issue.

When upgrading from trusty to xenial I see:
/etc/systemd/system/nut-client.service -> /lib/systemd/system/nut-monitor.service

But even a follow on remove, install, reinstall, purge - all of them just work.
Even so the conffile (wel lit actually isn't considered by dpkg as one) should be removed on upgrade.

OTOH the symlink alone doesn't "hurt" systemd or nut in any way which kind of means it will fail to qualify as SRU as you know better than I do.

Is thre anything else that comes to your mind one needs to really get to the upgrade/uninstall issue that you have seen?
