The various system init scripts are called in the proper order. After that, init sends a TERM signal to all processes. After a short delay, init sends a KILL signal to all remaining processes. Once everything in userspace is dead, it unmounts the filesystems and reboots the machine. -- Nathan Poznick <[EMAIL PROTECTED]> It is better to be beautiful than to be good.
