No, it will call the scripts in /etc/*-postinsts (it bails out of the
for loop if the post inst dir is there...)

Then opkg status file still shows the packages as just "unpacked". When
running the package manager (e.g. to install an unrelated package) opkg
starts to handle the postinst again...

Rather than updating the package managers database etc I rather feel we
should just not do the OE specific postinst if package management can
handle it.
