> It is highly unlikely that the configuration file on one distro is replaced with one that was shipped on a different one.

I think it's more likely than you say in cases that a configuration shipped is primarily a set of boolean values and enumerations of a limited set of strings, and the difference in distributions is mostly in choices of those values. The extreme example would be a configuration file that ships just one boolean setting. I think this unattended-upgrades case is closer to that extreme example than it is to openssh's sshd_config.
