Comment 1 for bug 644016

The "Restart to Complete Update..." message comes from indicator-session, and there's currently no means to change that string. Adding a task to indicator-session for advice from the Ayatana team as to how we might solve this.

The "Lock Screen" and "Switch from ubuntu..." options can be disabled by setting /desktop/gnome/lockdown/disable_lock_screen and /desktop/gnome/lockdown/disable_user_switching, which I'll add to ubiquity-dm now.
