Heh, hard power-off, resulting in unclean filesystems probably isn't what the original poster meant. For power off via button, init runs "sh /etc/rc shutdown", then sends all processes a SIGHUP, then waits 5 seconds. If there are any processes still alive it'll send SIGTERM and wait another 5 seconds. If any are still alive at that point it'll send'em all SIGKILL and wait another 5 seconds. It'll then tell the kernel to halt the system. So, slow /etc/rc.d/* script delaying the /etc/rc shutdown step? Or do you have some daemon which isn't killed by its rc.d script, nor by SIGHUP, thus requiring SIGTERM and at least 10 seconds? Philip Guenther
