Description of problem:
When starting the system I get error message on startup of aiccu and this is what systemctl status has to say:

matej@wycliff: ~$ sudo systemctl status aiccu.service 
aiccu.service - AICCU (AAutomatic IPv6 Connectivity Configuration Utility)
	  Loaded: loaded (/usr/lib/systemd/system/aiccu.service; enabled)
	  Active: failed (Result: exit-code) since Fri, 2012-12-14 06:14:59 CET; 1min 40s ago
	 Process: 885 ExecStart=/usr/sbin/aiccu start $OPTIONS (code=exited, status=255)
	  CGroup: name=systemd:/system/aiccu.service

Dec 14 06:14:59 wycliff.ceplovi.cz systemd[1]: Unit aiccu.service entered failed state

When I then start aiccu manually, everything works correctly:

matej@wycliff: ~$ sudo systemctl restart aiccu.service 
matej@wycliff: ~$ sudo systemctl status aiccu.service 
aiccu.service - AICCU (AAutomatic IPv6 Connectivity Configuration Utility)
