Well, yes, now that nvidia-common is forcing the dependency via
ubuntu-drivers-common. But they were not as of precise:
and such a dependency is undesirable.

We'd also need a debconf frontend which would mean bringing in the
grk3widgets aptdaemon stuff, which is undesirable as well.

I didn't mean re-implement the whole thing. ;-) But already we have
the QApt Worker which can do this, making duplication a needless

QApt is perfectly capable of providing installation stuff over DBus,
so it would be better from a dependencies/ISO space standpoint. Do you
know if ubuntu-drivers-common currently supports multiple backends,
and if it could be made to do so?

Well then an aptdaemon dependency is really unwanted in this case.
