cfengine vs all-etc-in-vc is like procedural vs functional programming;
one of them lets you describe in detail how the operation is going to be
done, the other one lets you describe the problem. That's probably not a
good analogy, but with cfengine I can describe the goal state of the system
and have cfengine sort out what needs to be done to get it there. Editing
etc and rolling out changes also means handling heterogenous systems adds
complexity to the system you use; cfengine effectively "factors out" the
common parts and lets you describe the small changes meaningfully.
