[Bug 1817380] Re: Migrate from cron to systemd timers

[Bryan Quigley]

Nope (although that is nice - I personally care more about the other restrictions you can do). I posted to devel-discuss about moving from anacron/cron to timers
https://lists.ubuntu.com/archives/ubuntu-devel-discuss/2019-February/018242.html

My count (in a disco LXD containder) we have 7 timers by default and 9
real cronjobs.  (Anacron is also done via systemd timer now, so let's
skip a step..)
