   7         ---help---
   8           If you say Y here (and to one of the following options) and create a
   9           character special file /dev/watchdog with major number 10 and minor
  10           number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
  11           subsequently opening the file and then failing to write to it for
  12           longer than 1 minute will result in rebooting the machine. This
  13           could be useful for a networked machine that needs to come back
  14           on-line as fast as possible after a lock-up. There's both a watchdog
  15           implementation entirely in software (which can sometimes fail to
  16           reboot the machine) and a driver for hardware watchdog boards, which
  17           are more robust and can also keep track of the temperature inside
  18           your computer. For details, read
  19           <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
  20
  21           The watchdog is usually used together with the watchdog daemon
  22           which is available from
  23           <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
  24           also monitor NFS connections and can reboot the machine when the process
  25           table is full.
  26
  27           If unsure, say N.

  34           Say Y here if you want to use the new watchdog timer driver core.
  35           This driver provides a framework for all watchdog timer drivers
  36           and gives them the /dev/watchdog interface (and later also the
  37           sysfs interface).

  41         help
  42           The default watchdog behaviour (which you get if you say N here) is
  43           to stop the timer if the process managing it closes the file
  44           /dev/watchdog. It's always remotely possible that this process might
  45           get killed. If you say Y here, the watchdog cannot be stopped once
  46           it has been started.
