Comment 2 for bug 758170

Puppet does not give you options on how to handle dpkg, as far as I know. This behavior is out of the ordinary for packages, btw. For instance, I've never seen this occur with Apache configuration. It is essentially *never* correct to overwrite a config file. You shouldn't even ask. It should be assumed the administrator has read the upgrade guide before upgrading, and will adjust their configuration file accordingly.

There is no situation in which the distro's default configuration file will ever be correct for my systems.
