This would be trivial to implement. Additionally, I'd personally think init(8) should be taught about watchdog facility. For panics, I think we should have the disk driver to "pat" watchdog rather than disabling it in their write success callback? Another thing is that ddb should be able to disable watchdog when it's waiting for keyboard input (or received first user input) I think.
