I have it in mind but did not implement it yet. The idea is to not
extract debs that are coming from isar-apt into the DL cache. Match by
name+md5 just like the current detection mechanism does.

No and i do not see how to involve that variable here. We just copy all
debs we know into the cache of the rootfs, which ones it will actually
install depends on which repos it uses.
So even if a ton of debs become potentially available, only the one
from the base-apt repo Packages.gz can be installed in practice.
