I stand corrected.
Interesting. Maybe the arbitrary loop thing can be documented too in
the policy, or otherwise it should be not allowed. Interesting that

for normal dependencies, that is just need the other software unpacked
to work, and one for must not be configured until other ones is
configured. This can probably help a lot.
