One way to get this working would be with APT::Update::Post-Invoke hook,
what /etc/apt/apt.conf.d/80debtags does.  This would work today for
"full" debdelta upgrades that were going to be applied immediately
(otherwise it would download potentially unapplied upgrades).

I am not sure if there's a good way for packages running on these hooks
to receive the list of packages to be installed/upgraded.

In that case, a kind of APT::"Install"::Pre-Invoke (if "Install" or
equivalent would exist, I don't think that it does now) would be ideal.


Cheers.
