└─>Update boot-enabled watchdog until userspace takes over
In linux kernel since version 4.2 (release Date: 2015-08-30)
The default watchdog behaviour (which you get if you say Y here) is
to ping watchdog devices that were enabled before the driver has
been loaded until control is taken over from userspace using the
/dev/watchdog file. If you say N here, the kernel will not update
the watchdog on its own. Thus if your userspace does not start fast
enough your device will reboot.
