Comment 6 for bug 397324

In future we want to distinguish between updates that will require a restart, and those that won't, before you even download them. That way you can click an "Install and Restart" button that doesn't need to prompt you later about *really* wanting to restart; it will all happen in a single action.

To address the points in order:
1. As long you don't restart, you are still running the old, insecure versions of the packages that required a restart, therefore the update has *not* completed.
2. You should not need to worry about closing all running apps; that's handled by session management.
3. There are bigger problems with the sentence: the phrase "In order to" is a needlessly long version of the word "To", and the "it" is ambiguous (does it refer to the "system", or the update?).
4. Even if restarting is scary for Windows users (which seems implausible), we don't do ourselves any good by pretending a restart of Ubuntu is anything other than a restart. I think almost everyone would be unpleasantly surprised that a button labelled "Use Latest Version" restarted their computer.
5. What?
6. Same as #2.

So as far as I'm concerned, this alert would be fixed if the text was changed to: "The computer needs to restart to finish installing updates. Do you want to restart it now?"
