Cron to Systemd Timer migration
Notes
Cron job that should be migrating should only be those that are in a package that already depends on systemd
Create packaging guidelines proposal regarding systemd time units with samples.
Should time units be bound to their corresponding service unit so they start and stop when unit is started?
Add requires to cron to packages that do not depend on systemd
Sample
ackme.timer
[Unit] Description=Ackme Sample Timer Unit BindTo=ackme.service [Timer] OnCalendar=daily ExecStart=/path/to/script [Install] WantedBy=multi-user.target
ackme.service
[Unit] Description=ackme Documentation=man:ackmed(1) [Service] User=ackme ExecStart=/usr/bin/acmed --daemon [Install] WantedBy=multi-user.target
