Package: udev Version: 231-6 Severity: wishlist Perhaps on upgrade instead of saying addgroup: The group `input' already exists as a system group. Exiting. say nothing, and instead just say Adding group `input'. if adding.
That way you need only make one message once, instead of a message upon each upgrade. And it is a message about doing something, instead of a message about doing nothing. No need to distract system administrators with a message about doing nothing, each upgrade.
