I haven't seen any code of the debconf part yet, but it should also be
implementable in the python based backend.
Since PolicyKit-1 isn't available in KDE/Kubuntu yet I focused on the
0.4.x series of PackageKit. But Lucid will very likely ship with 0.5,
so I am going to catch up with the new features soon.
How does your workaround work? Do you just run "apt-file -N -l search
PATH"? This should not be hard to implement. But how do you handle
apt-file update? Should this happen after every cache update?
