Thx for the fast feedback. Good hint with the man page, I'll have a more detailed look on the page. I think when you need to stay a bit independent from systemd and don't have a dbus interface which can be used for synchronization there is probably no other way then the classical one. But in case I'm starting in such a well prepared environment like the one provided by a systemd service, I hopefully will not run into any troubles even if my daemon is "missing something of the required initialization sequence or doing it wrong" ;) Best regards Marko Hoyer Software Group II (ADITG/SW2) Tel. +49 5121 49 6948 _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
