systemd-cron does that:


I also wrote a proposal for the policy here:


The only thing that systemd-cron needs to close last remaining bugs
is a rewrite in a lower level language with a smaller runtime
(C or C++) there's a rewrite done in Rust; butI have no
idea on how to package that in Debian & the runtime is huge.

That's only about 550 lines of python code to rewrite that
read some textfiles in /etc/cron.d (crontabs)
& output other text files in /run (systemd timers & service);
I'll do that "someday".

Then crontab would need to be spun out of cron.deb so that
it could be shared by two implementations.

Vixie cron could be patched to also work this way to avoid noise in log files.
