Systemd tips and tricks


Recommended Posts

Whilst there are some threads concerning systemd there does not seem to be a thread about using systemd that I can find so this is just such a thread.

This is a thread to post useful information on the general usage of systemd for whatever os.


My tip is a little outside my knowledge zone but I can see that it looks very useful. :look:




Installed as a service, it runs in the background and whenever a matching messages is added to the journal, the corresponding action is triggered. Exactly what I was looking for.

For example, an error can sometimes occur leading to the network being down, as the interface goes down with a speed/duplex mismatch error. This doesn't happen very often and is easy enough to fix once the problem has been identified, but now I don't have to, thanks to a simple rule like the following:


trigger=systemctl restart network.service



MESSAGE=sky2 0000:02:00.0 net0: speed/duplex mismatch

See I told you it was a useful tip.
