Option to automatically reboot Ubuntu for security updates

[warg]

Yep. For those cases it shouldn't be too bad: The fixed timeslots/dates can be communicated/planned accordingly and if it's on demand and no admin is available, the users can get told that they should be worried only if downtime is >1h or something like that. That's at least better than no patched server and in worst case coming home and finding a disaster .

This can be automated today with ctfreak which can reboot a system if certain conditions are met. Would be good to document such options.

@nebulon just for information - livepatch doesn't mean you don't have to reboot - it just lets you postpone that moment as convenient.

For sync - a good practice on old good *nix is to issue sync twice before reboot - to make sure the buffers dumped for sure.

On the reboot automation using third-party apps - it's doable; everything is, but why, if you can just add it inside of the system?
