I'm not sure that I understand. This is in the context of handling daemons that fork and background themselves, is not it? If so, no normal parent would be able to detect that this has happened because the process would have already been reparented by init before the SIGSTOP signal is sent. So it does rely on the special properties of PID 1, namely its adoption of all processes that have abandoned their parent process. -- Russ Allbery ([email protected]) <http://www.eyrie.org/~eagle/> -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
