You can invoke another service with OnFailure= as soon as your service
fails. Then, you can pull the failure reason out of the original service
via the bus and act on it.

OnFailure=failure-handler@%p.servince

and then in failure-handler at .service you take %i and use your own bus
client or "systemctl show -p" to query the "Result" property which will
tell you the reason the unit failed.
