Path string // Args holds command line arguments, including the command as Args[0]. Argv[0] process (self-spawn), then spawning target process (with Setsid: true), and then exiting first spawned process. It seems good strategy for immediately disowning is spawning os. Provided that the daemon is not already a process group leader (which it will not be following the fork performed above), this will: start a new session, with the daemon as session leader and with no controlling terminal, and start a new process group, with the daemon as process group leader.
