My biggest annoyance is "systemctl status" gives you just enough of the service's log to make the output take up most of the terminal each time you run it but never enough of the service's log to get a useful picture of what's actually happened with the service lately.

Not to mention unless the problem with the service completely prevented it from running (it advises some commands to run in that case) you're supposed to just always remember "journalctl -xeu $SERVICE" was the incantation, less you want to go look up the flags again or manually parse the entire "journalctl" output.

Overall I generally like systemd though. The syntax can just be a burden sometimes.
