Thinking about this slightly on a slightly higher-level:

If you are implementing organizational processes similar to the
Visible Ops recommendations, you might want to think setting up a
modeful policy; that is, support Cfengine running in 'change window'
mode, and in a validation mode (which would be the default).

Part of the 'change window' mode operation would be to update all
tripwire-style databases so that any valid changes made due to
promises that need to be kept do not trigger alerts. Then, in
validation mode (presumably most of the time), any changes detected
would be invalid and reported (you need to maintain either good
whitelists or good blacklists for this kind of design to work well and
scale).

I would also like to point out that there is more to system state than
file contents (bits on disk). You also care about the status of
services (processes running), and diffs in that space are not captured
by file-level change management.
