Unless I'm doing something wrong, google knows nothing about the pdfs on
www.cfengine.com which so far seem to have the most information.

If it's not simple enough to understand from the literature, it is
probably a waste of everyone's time to go any farther. I haven't read it
all yet but so far everything I've found is very abstract, hides _how_
things are done, seems to assume that everyone involved already knows
the underlying programming language, and that everyone that can touch
the conf files can control the whole farm of machines (or at least the
ones that expect to be conrolled). As a sysadmin, the _how_ is the
important part to me, but an abstraction is good if it permits
separating the knowledge and control by specialized roles. What I'm
looking for is how an application developer who introduces
version-related differences in the application config files can supply
the necessary changes for the cfengine conf (preferably without being
able to affect other apps) and how the operations person scheduling an
up (or down) grade of this app on a particular set of machines can be
sure the versioning of the cfengine conf matches the app version in
question without having to know the details of the differences. There
are obviously other issues in mapping the real world to an abstraction,
but this is the one that I need to understand up front - and I'd think
everyone on this list would have had to go through this planning
exercise before choosing the tool to best manage it. I can see from
cfengingEnterprise.pdf that there is a concept for splitting
responsibilities across teams but don't see any real mechanism for
making that happen.
