Indeed, I didn't bump it for the "machine" change.  The idea
Warner attempts to implement is to bump a major whenever a
backwards incompatible change is made, and bump a minor when
a change is made such that a backward compatibility is not
affected.  This would allow for config versions >= the
required version to work.  I'd then bump the config version
along with the change, and bump the required version in
makefiles when doing a change to conf/files* (in this
particular case).
