 config is pulled through apt preconfig hook, but that script only is
allowed to do the debconf question dialogues and /nothing/ else. The
actual code still has to be in the postinst that extracts the
informations from the debconf cache and does still run after the package
and all its dependencies are unpacked. Given that it's only needed to be
done on upgrades you can safely assume that at least _a_ version of the
package was configured before.

 From the worst-case scenario Markus pointed out I rather would only go
with a NEWS.Debian entry informing the people, too.

 So long,
