Subject: systemd timers?

Package: cron-apt
Version: 0.13.0.1
Severity: wishlist

Hi,

would you be open to a patch that adds the possibility to use systemd
timers? Quite some packages in Debian have adopted a way to run through
systemd timers and systemd units on systems that have systemd, falling
back to the "old" cron job configuration if there is no systemd. for
example, apt is doing it this way.

I am attaching the four preliminary systemd units I am using on a test
system without problems. You might notice that they're using systemd's
RandomizedDelaySec feature and call cron-apt -i instead. I find that
more elegant.

The systemd units would also make it easier to run with reduced
privileges, having parts of the file system read-only and have other
nice security features. My preliminary units don't do that yet, but I
would be willing to do that if there is a chance to get the work into
the package.

Let me know what you think.

Greetings
Marc

Hi Marc

Sorry again for the late reply. Yes such a patch can be considered.
It must be clear on how the cron-fallback would work though.
