If you are installing stuff regularily, you might also want to consider
having your local mirror. If you freeze the udeb parts of this and only
trigger an update of that part manually once you also update
kernel/initramfs, you can be sure everything will still be the same.
(And together with some snapshotting one can also choose to revert
other changes in case they create problems).

(Though it would be even nicer if one could tell the installer to use
some snapshot directly, but I never understood the distribution
selection code of d-i and fear it is rather impossible).
