My experience with it was on RHEL4.x some years ago, trying to install a bunch of stuff not from the official repos or EPEL. (I think it was Puppet, at the time.) Holy crap. It took me a week. It was more complex (or, almost equivalently, poorly documented) than the old AT&T Merlin PBX+voicemail system. The only thing I recall offhand was the hugeness of the namespace for roles (?) and actions (?). Every time I punched a hole to allow a specific thing to happen, something else blocked the action with cryptic logs in obscure places. I felt like a blind person, trying to find their way through a maze.
