I'm not disputing anything you're saying about the importance of patches and updates, only the importance of being able to control WHEN they happen and WHAT to apply. But you've already indicated that makes me--and anyone else *cough cough* who inquires about how to do such a thing--an 'idiot'. So there's not much to discuss beyond that.
