The FAI people (Fully Automated Installer (for Debian)) have exactly
these issues. They have a program called fai-divert which can be
useful to make things less interactive and doesn't rely on
re-compiling the package.

Furthermore, I notice you're not setting the environment variable
DEBCONF_FRONTEND to noninteractive, which I would advise.  See also
debconf(7) for ways to use your local debconf repositry for a remote
host.

Sadly, not all interactive packages use Debconf, but the number of
aberations is reducing all the time.
