I've seen people prefer type=forking over type=simple for the sake of
checking syntax before starting *depending* units. I'm not particularly
convinced myself that this is valuable, but whatever it's worth,
ExecStartPre should achieve the same goal (depending units are not
started if syntax check fails).
