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. -- Andriy Gapon
