It would be a lot simpler to do "transactional updates" by using Git FS like Webconverger does to roll out updates. That way clients can see the exact changes at https://github.com/Webconverger/webc https://github.com/Webconverger/webc and even roll back or use branches. Not to mention enjoying all the other git compatible tooling.
