Looks good and simple. A few suggestions:

* Perhaps check the format of the file first with
  debconf-get-selections -c
* Provide a way for the user to change debconf settings on the fly.
  e.g. settings based on hostname.

Yes, the pre-seeding should happen before the packages are installed.

Once the package is installed you start getting people saying "debconf
is not a registry".

Although mileage varies per package.

Unfortunately with this solution none of the packages already installed
in the target are pre-seedable, i.e. packages in the tarball. But you can't
have it all.
