Seems like you have an axe to grind with systemd because it replaced your familiar (but extremely cruddy) init system and now you refuse to debug the problem because you prefer being able to blame systemd.

There is so much granularity and flexibility in what you can do it seems rather unlikely you cannot make it happen correctly. And if it is truly a bug... open an issue? They're rather responsive to it. And it isn't like the legacy init systems were bug free from inception (well, lord knows they were still chock full of bugs even when they were replaced).

Edit: sitting here with a grin .. HN downvoting the advice of checking logs, debugging and opening an issue. I wish the companies y'all work at good luck.. they'll need it.
