  Oops, I missed that part :D. You don't
  want to drop it completely.

FWIW

Neither for my Ubuntu, nor for my Arch Linux install I need much
timers.

I'm booted to Arch Linux now, but it should be similar for my Ubuntu
install:

  $ systemctl list-timers --all

  4 timers listed.

However, backwards compatibility might be useful for those who make
intensive use of individual cron jobs that aren't provided by packages.
Should they be forced to redo all the work they already have done?

Anacron/Cron needed by default anymore?

2019-02-12 Thread Bryan Quigley 
Hi all,

Systemd timers seem like a fine replacement[1] for cron/anacron and is
installed by default.  Further, many of our default services have switched
to them.

Based on the recent change [2] in Debian, I don't believe anacron is needed
anymore.  I'm curious if anyone sees a specific need for cron to be there
as well.

Based on a disco desktop current jobs:
apport - clean all crash reports which are older than a week.
apt-compat - says to prefer the systemd timers
bsdmainutils - BSD mainutils calendar daily maintenance script
cracklib-runtime - make a wordlist for stronger password checking
dpkg - Backup the 7 last versions of dpkg databases containing user data.
logrotate - skips if systemd is installed
man-db - skips if systemd is installed
mlocate - regenerates locate database
passwd - backups passwd group shadow gshadow
popularity-contest - sends package info
ubuntu-advantage-tools - runs status and stores in a cache
update-notifier-common - Try to rerun any package data downloads that
failed at package install time.

Happy to start tackling those that are left if there is agreement to move
to systemd timers / drop anacron/cron.

Thanks!
Bryan
