The idea was that the change in PolicyKit would be accompanied by a
default set of roles, and a nice user interface for assigning users to
roles. Unfortunately, with the constraints of time, it became clear that
this all (and especially the GUI) wasn't going to be there for Fedora
12. So, PackageKit needed a fixed policy for all users. For each action
(install signed packages, install unsigned packages, remove packages,
etc.), it needed to allow, deny, or ask for the root password.
