When using the action after updates have finished option, add a delay and notification. Something like "Discover has finished the requested updates and will [ACTION] in [TIMEOUT] seconds". This way, users have an option to cancel it if they need. Especially as a reboot is a potentially destructive process if the user has work open they haven't saved. This might happen if a user hits update all in Discover, sets it to reboot, but then forgets it is updating in the background and continues to work on a file or project.
> Especially as a reboot is a potentially destructive process if the user has work open they haven't saved It shouldn't be; apps are supposed to prompt the user to save, and cancel logout if the user makes no choice. Currently this isn't happening, which is tracked by Bug 499260. Fixing that seems like the better course of action. *** This bug has been marked as a duplicate of bug 499260 ***
