Packaging issue: .service files are no conffiles (due to /lib) while init scripts are conffiles and hence remain longer on the system upon package removal without purging

I just noticed, that /lib/systemd/system/screen-cleanup.service isn't
actually a service file, but a symlink to /dev/null. This wasn't obvious
to me from your first email.

So technically, you already mask the sysv init script.
I assume that is because you ship a tmpfiles snippet,
/usr/lib/tmpfiles.d/screen-cleanup.conf (*) which implements the
equivalent functionality.

IIRC, dh_systemd_* only operates on real service files, so won't help
you, as this is a very specific use case.

So, option 2) might actually be the proper solution for your specific
case after all. If you create that mask dynamically via postinst, this
should be done in /etc though, I think.

But let me first think about this more, before you go on implementing
something.

(*) you seem to ship an empty /etc/tmpfiles.d directory for no apparent
reason
