I think Seth explained the details similar to what we do.  We do not use
cfengine at the moment; we stick every configuration change into an RPM.
Sometimes our RPMs use triggers to modify existing config files.  Other
times, our RPMs install a foo.conf.cisco and move it on top of the RH-
provided one in %post.

This allows us to version every configuration change across our
environment just using the RPM database.  We have an inventory agent
that runs daily on each host and reports back into a central repository.
We can then query "which hosts are running cisco-sendmail-config < 1.5"
and decide if we need to push an update or escalate to a sysadmin, etc.
