Ah, ok. I think it was just a misunderstanding about whether or not
aptdaemon was a requirement, due to its status as a hard dependency.
Glad to see that resolved, and no hard feelings at any rate. I was
just a bit annoyed at the (apparent at the time) unilateral
introduction of a new dependency that duplicated existing
functionality to a core package, without any discussion, so I'm sorry
if I came off as a bit terse in my replies. :)

So if I understand correctly, detect.py currently loads a backend
plugin from /usr/share/ubuntu-drivers-common/detect/ (currently the
PackageKit plugin) and uses the what_provides_modalias() and
system_driver_packages() methods in PackageKit.py for discovering
which packages need to be installed? And then if I were to write a
backend for QApt I could write a analogous QApt.py that implements
those two functions and install that to
