It's ugly indeed. Although using OnFailure would probably be "the
systemd way".

Can't we just call journalctl <> from OnFailure to get the error output?

Having a wrapper would definitely be the easy way.

Though I would be more inclined to use an OnFailure script instead, if
we can actually manage to get the output from systemd/journalctl.
