Editing a systemd Unit File

While setting up cron and msmtp I needed to make sure crond was started with the '-S' argument to ensure cron used sendmail instead of syslog. Arch has recently moved to systemd, so the change I needed to make necessitated editing the systemd unit file for cronie:

kjones /usr/lib/systemd/system $ sudo vim cronie.service
Description=Periodic Command Scheduler

[Service] ExecStart=/usr/bin/crond -S ExecReload=/bin/kill -HUP $MAINPID KillMode=process Restart=always

[Install] WantedBy=multi-user.target

and reloading the unit file for the change to take effect:

kjones /usr/lib/systemd/system $ sudo systemctl reload cronie

and finally checking the status of cronie:

kjones /usr/lib/systemd/system $ sudo systemctl status cronie
[sudo] password for kjones:
cronie.service - Periodic Command Scheduler
