Quite a common use case for Linux is where PC's are installed on computers without internet access, or where internet access is very expensive. So, enter PackageKit. You insert a CDROM or USB pendrive with updates on. The following UI appears: You click “yes” and then the update icon appears as if you were online. You click “Update system” and then the update proceeds as if you were online. Plus, because the local media is an actual repo, you can also use the Add/Remove software tool as normal. Nothing is in git master yet, although I've got a local branch that I'll probably merge after 0.1.10 is released. Comments appreciated.
