That at least contradicts my testing with opkg/ipk.

If /etc/ipk-postinsts is not there and /var/lib/opkg/status is there
(package management installed), then run-postinst runs "opkg configure",
which takes care of postinsts just fine.

Reading the code at least let me to believe that this is true for deb as
well.

Not sure how it works with rpm though. How do you came to the conclusion
that this only happens when using rpm?

Yeah will do when I have a solution which I am happy with.

Before that, I rather prefer understanding the whole issue and try to
come up with a solution that works on first regression test (rather than
try and error)...
