I have one use case in mind and it's a truly special case.
I want rc.d/watchdogd to gracefully stop watchdogd and to disable the
watchdog timer when the stop action is requested manually.  And I want
it to stop watchdogd and set the watchdog timer to a special shutdown
timeout during the shutdown.  If the special timeout is configured, of
course.
