vixie-cron is what everybody is/was using for quite some time, and all
distros patched it heavily. Upstream is gone, so it's effectively
abandoned. Suse was using it as well, but migrated to cronie. Found this
page about that migration: https://en.opensuse.org/openSUSE:Cron_replace

cronie exists in debian experimental, but apparently abandoned (
https://tracker.debian.org/pkg/cronie). It doesn't exist in Ubuntu.
Upstream is Fedora, at https://github.com/cronie-crond/cronie

I also found some documentation showing how to use systemd timers as a
replacement. It's not a direct replacement, though:
- doesn't parse crontabs, has its own mechanism
- doesn't send out email by default, one needs to use Onfailure and point
it at a script that will send out the email

We could check the patch that implemented MAILFROM and adopt it. I'm not
sure if suse used the same one attached to the bug I mentioned before.
