Ok, I guess I forgot to mention why the issue mentioned by Paul happens
and run-postinsts doesn't do its job.

Well, as it happens, opkg postinstall creates a S98run-postinsts script
in rcS.d that will overwrite run-postinsts one.

We could fix that by making opkg create the script on position 97 and
both scripts will run in this case. Opkg one will fail, since there is
no metadata available, but run-postinsts will work because the
postinstalls are saved in /etc/(ipk|deb|rpm)_postinsts directory.

The only 'issue' remaining is the lack of metadata if one chooses to
manually install a PM when 'package-management' is disabled.

Now that I think about it, this might be a better alternative. But I
didn't test it though. It just came to my mind...

What do you think?
