118c2ecf20Sopenharmony_ci	  character special file /dev/watchdog with major number 10 and minor
128c2ecf20Sopenharmony_ci	  number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
138c2ecf20Sopenharmony_ci	  subsequently opening the file and then failing to write to it for
148c2ecf20Sopenharmony_ci	  longer than 1 minute will result in rebooting the machine. This
158c2ecf20Sopenharmony_ci	  could be useful for a networked machine that needs to come back
168c2ecf20Sopenharmony_ci	  on-line as fast as possible after a lock-up. There's both a watchdog
178c2ecf20Sopenharmony_ci	  implementation entirely in software (which can sometimes fail to
188c2ecf20Sopenharmony_ci	  reboot the machine) and a driver for hardware watchdog boards, which
198c2ecf20Sopenharmony_ci	  are more robust and can also keep track of the temperature inside
208c2ecf20Sopenharmony_ci	  your computer. For details, read
218c2ecf20Sopenharmony_ci	  <file:Documentation/watchdog/watchdog-api.rst> in the kernel source.
228c2ecf20Sopenharmony_ci
238c2ecf20Sopenharmony_ci	  The watchdog is usually used together with the watchdog daemon
248c2ecf20Sopenharmony_ci	  which is available from
258c2ecf20Sopenharmony_ci	  <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
268c2ecf20Sopenharmony_ci	  also monitor NFS connections and can reboot the machine when the process
