Comment 3 for bug 736844

As I wrote in my initial report:
"The message should at least propose to logout / login to complete the installation, or the installation post-install scripts should warn / force this. Ideally this should not be necessary so we have the best user experience."

Right after installation is when I would expect a more useful message to pop-up in notifications / power-menu (forgot what it's called), much like updates that require a reboot.
