10b7e04f8cSWim Van Sebroeck	  If you say Y here (and to one of the following options) and create a
11b7e04f8cSWim Van Sebroeck	  character special file /dev/watchdog with major number 10 and minor
12b7e04f8cSWim Van Sebroeck	  number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
13b7e04f8cSWim Van Sebroeck	  subsequently opening the file and then failing to write to it for
14b7e04f8cSWim Van Sebroeck	  longer than 1 minute will result in rebooting the machine. This
15b7e04f8cSWim Van Sebroeck	  could be useful for a networked machine that needs to come back
16b7e04f8cSWim Van Sebroeck	  on-line as fast as possible after a lock-up. There's both a watchdog
17b7e04f8cSWim Van Sebroeck	  implementation entirely in software (which can sometimes fail to
18b7e04f8cSWim Van Sebroeck	  reboot the machine) and a driver for hardware watchdog boards, which
19b7e04f8cSWim Van Sebroeck	  are more robust and can also keep track of the temperature inside
20e403149cSDirk Hohndel	  your computer. For details, read
2174665686SMauro Carvalho Chehab	  <file:Documentation/watchdog/watchdog-api.rst> in the kernel source.
22b7e04f8cSWim Van Sebroeck
23b7e04f8cSWim Van Sebroeck	  The watchdog is usually used together with the watchdog daemon
24b7e04f8cSWim Van Sebroeck	  which is available from
2501028829SRandy Dunlap	  <https://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon
2601028829SRandy Dunlap	  can also monitor NFS connections and can reboot the machine when the
