I'm just thinking how Solaris 10's SMF can solve this. As far as I noticed, it somehow keeps track on children too, so if the "start method" only does something then exits, it still knows that the service is running since there is child(ren) process(es) of the start method in the system. I am not sure however, but as far as I remember/experienced. Upstart may does not have this feature however ... -- Gábor
