Bug#1106000: systemd-cron: purging "anacron" after systemd-cron will publish message with level 'error' on journal, once

[Alexandre Detiste]

Package: systemd-cron
Version: 2.5.1-1
Severity: normal

1) systemd-cron should always ignore /etc/cron.d/anacron to begin with,
   -> include this upstream

2) in Debian /etc/cron.d/anacron is harmless anyway (it checks /run/systemd/system)

3) the only worrying thing is the red line in journal
   -> it's a false positive due to the fact there is a race-condition
      between 'dpkg --purge' and the auto-triggered 'systemctl daemon-reload'

4) add status of cron & anacron in future bug report (purged or not)
