Comment 9 for bug 1346355

System-related communications should present in the upper-right corner at the indicators. The indicators exist as an interface layer between the System and the User.

Application-related communications should present at the Launcher.

The requirement that the computer be rebooted is a System-related event; therefore, the communication that this event is needed needs to present at the indicators--not the Launcher, and not some ephemeral popup.

If an Application needs to be restarted, then the appropriate communication location would be at the Launcher or within the Application itself.

The ONLY instance where a popup should be used is in situations where an IMMEDIATE response is needed to proceed: for example, the user is trying to access something that requires a password. A prompt pops up to allow entering the password.
