home made (F17) systemd script not working F14

[Gary Stainburn]

The following file is the one I created for my F 17 test bed system which 
worked fine.

I've not put it onto my production F 14 system but it won't start. 
Enable worked but the service didn't run on restart

I have no knowledge of systemd so I'm struggling here.
