Sorry, friend but you are wrong on this. A simple change would fix the problem which is don't restart the computer! You can update anything and do anything when the computer is plugged in but please don't restart the computer or at least let users decide when they want to restart their computers. Even fedora does a better job with software updates. There is a checkbox when you turn off or restart the computer. If you check it, fedora will install updates and shut down/reboot. Why is this so difficult?

Security without usability is worthless.
