I think that we need to do the following:
1) Do not (directly) install any files that the user might change.
   (master copies of some will be needed)
2) Run a script (cf etcupdate and postinstall) that ensures that
   the required config files exist and contain the required entries.
   (needs to be able to be run on a system without a source tree!)
3) Make sysinst run the script.
4) Have an option in sysinst to delete the old config files.
