Dear Maintainer(s),

cachefilesd has been flagged by Lintian as shipping a sysv-init
script without a corresponding systemd unit file. The default init
system in Debian is systemd, and so far this worked because a
transitional sysv-init-to-unit generator was shipped by systemd. This
is in the process of being deprecated and will be removed by the time
Trixie ships, so the remaining packages that ship init scripts
without systemd units will stop working.

There are various advantages to using native units, for example the
legacy generator cannot tell the different between a oneshot service
and a long running daemon. Also, sanboxing and security features
become available for services. For more information, consult the
systemd documentation:
https://www.freedesktop.org/software/systemd/man/systemd.unit.html

You can find the Lintian warning here:

https://lintian.debian.org/sources/cachefilesd

In case this is a false positive, please add a Lintian override to
silence it and then close this bug.

Thanks!

Note that a .service file is attached to:

Dear Maintainer(s) of affected packages, these bugs have been open for
more than 2 years now. Policy was updated to make units mandatory for
system services. The removal of compat with sysv-init scripts from
systemd has been postponed from trixie to forky, but it is now
approaching. In approximately a month's time, this should hit
unstable, if everything goes well.

Therefore in order to ensure the remaining bugs do not fall through
the cracks I am raising severity again, as there is a very high chance
the affected packages will stop working as intended in about a month's
time in the default setup.

As already mentioned in the original bug report, if your package is
not intended to work as a systemd service or under systemd at all,
please feel free to downgrade or close+wontifx or anything else as you
see fit. The severity raising is not intended to make anyone support
scenarios they don't wish to support, but simply to ensure attention
is given to the issue, even if just to close+wontfix. Also the bugs
were opened based on Lintian reports, and it is possible that there
might be false positives.

Thanks for your work and understanding.

cachefilesd is one of the last packages on my system w/o a systemd service
file and systemd-sysv-generator complains loudly. The upstream package
does contain a .service file and the attached patch is my naïve attempt to
make use of it.

A dpkg-buildpackage run appears to complete and the resulting package does
include the .service file now, but I don't know the whole dh_ machinery
well enough to check if that's sufficient.

Please review.

Thank you,
Christian.
