On the second run, the config file does not yet exist. There are edge
cases, such as a debconf question being added to a package that is
already installed, where the config file may exist and the questions
have not yet been asked, so the user would be prompted and then their
answers written over with the values from the config file.

By doing this you eliminate preconfiguration, so the user has to wait
around for your package to be installed before they can answer its
questions.

It would be better to test for the specific case where the config file
already exists, and work around just that case.
