	  If you say Y here (and to one of the following options) and create a
	  character special file /dev/watchdog with major number 10 and minor
	  number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
	  subsequently opening the file and then failing to write to it for

	  The watchdog is usually used together with the watchdog daemon
	  which is available from
	  <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
	  also monitor NFS connections and can reboot the machine when the process
	  table is full.

	  The default watchdog behaviour (which you get if you say N here) is
