I still think disabling suspend from shutdown.c, at the same time as creating /var/run/nologin might be the best way to go, to avoid any possibility of untimely suspending once committed to shutting down. For one thing, shutdown's -o flag bypasses using init and calls halt or reboot directly, though I don't know if anyone uses that. For another, if shutdown fails for any reason, or is cancelled by signal by the user .. or in any case, I gather .. finish() removes /var/run/nologin, and could also there reenable suspend, covering Anthony's point. cheers, Ian
