File content is just a small part of what puppet classes generally do. Average module if coded properly will include number of operations like starting/configuring services, cron jobs, editing files, installing packages, etc. and I think the only way to satisfy that average change control 'revert' is to code the reverse operation while you code the change. I would compare it to rc init scripts what have 'start' and 'stop' operations. It is all a matter of coding standards and defensive design. -Peter
