Experiment with Dpkg::Pre-Invoke or Dpkg::Post-Invoke
We should experiment the configuration of APT through /etc/apt/conf.d and the directives Dpkg::Pre-Invoke or Dpkg::Post-Invoke.
This could allow automatic changelog entries (is this desirable?) and better following of modifications made from the initially installed configuration files: which means clearer diffs!
