If I have existing infrastructure, are you able to generate a diagram/model of the current state given sufficient permissions?
I recall trying to convince you to experiment with that when you were building Chef but you'd just come out of working with finance stuff so understandably felt that an uncontrolled change should always be dealt with via emitting a resume generating event.
I continue to believe that for small non-bank organisations, when somebody gets paged in the middle of the night "whatever gets production to stop being on fire the fastest" is completely legitimate and systems automation tooling should support handling the config reconciliation -after- it's back up.
... but enjoy your launch day, having waited this long to argue my case again I can leave it a while longer :D
