Computer Tips - systemd: restart down service

Date: 2019nov11 Product: systemd OS: Linux Q. systemd: restart down service A. A big benefit of systemd over traditional service launchers is its ability to monitor services and optionally restart them if they stop unexpectedly. In the past I would write little scripts to ensure important services were running. Now you can simply use Restart=always in the service's unit file. This will restart the service if crashes. For example, for dnsmasq:
[Unit] Description=DNS caching server. [Service] ExecStart=/usr/sbin/dnsmasq -k Restart=always <!--- KEY LINE [Install]
There are other choices for the Restart option
