Ah, but see, that is only one minor and commonly seen problem, and they get much worse very quickly the more you look. I suppose if the only thing you care about is using it (instead of sharing, such as the back and forth between BSD and Linux, which is something I used to think was a great idea) there are no problems. Not only does it create more work for the people that have to learn to use systemd, it makes more work for those that don't. I suppose this is acceptable? To me, it is not.RTFM and get over it.
I used that a LOT in the past. Last time I tried was on a RHEL VM and it didn't work. I stopped using it pretty much immediately so that I wouldn't continue to rely on it and forget how things are done with systemd. Maybe it is just Red Hat that doesn't use it, or those VMs, since I don't know much about them other than they were used to teach all the new RHEL stuff. With previous versions I used "service" worked just fine.On a debian system I use the "service" command anyway, works more or less the same no matter what init system you use.
