Package: popularity-contest
Version: 1.67
This is regards to the popularity-contest cron job. I'm looking into
running systems without anacron/cron installed - instead using systemd
timers.
My suggestion would be to remove the what to do functionality from the
cron job/timing bits to another script - say popcon-runner.
The cron job could then be something like:
# skip in favour of systemd timer (from logrotate)
if [ -d /run/systemd/system ]; then
exit 0
fi
<anything else cron specific needed to schedule when it runs>
popcon-runner
And creating a systemd timer/service for those that have systemd installed:
Timer File
/etc/systemd/system/timers.target.wants/popularity-contest.timer
[Unit]
Description=Sends popularity contest data
[Timer]
OnCalendar=daily
AccuracySec=24h [ Can change this to be less accurate to spread
server load, etc)
Persistent=true
[Install]
WantedBy=timers.target
Service File
/usr/lib/systemd/system/popularity-contest.service
[Unit]
Description=Sends popularity contest data
[Service]
ExecStart=/path/to/popcon-runner
Nice=19
IOSchedulingClass=2
IOSchedulingPriority=7
(can easily set nice levels, IO limits)
PrivateTmp=true
PrivateDevices=true
There are a bunch of other restrictions that can be placed on it via
systemd Private directives.
Thanks!
