[systemd-devel] Calling shutdown while executing a service

I added that line at the beginning of die(), but that did not result in
additional screen messages. But I am sure that the delayed shutdown
happens because systemd is waiting for my service to finish. Is there
another way to prevent that, than adding an exit command at the end of
die()?
