Answer 1

As of docker implementation 1.0.1 (Server /client API 1.12), there is only support for pause/resume operations.

But as far as snapshotting of processes (in commits + push) are concerned, these don't work (not supported, though I've not checked documentation)

In summary, 1) Preserving state of running processes is not possible! 2) All changes being made to file system (persistent storage) can be saved (and can be committed + pushed to repository).
