Yeah, me too (a stronger / more statically) typed language. But you're up against a potentially changing state -- the file system. So that only gets you so far. Idempotency is very hard to achieve. What gets me is there is an excellent tool -- rsync -- which is extremely fast and idempotent. The various config tools make far too little use of it.
