When using the Web Console, there is a mistake regarding the revision picked up to revert the server.

Right now, the revision selected to revert is the one that corresponds to the updated state performed by the current update. Reverting to this state will do nothing since you will be reverting to the current server state.

See for example the attached screen shoot. The "revert" button will revert the server to "fe043223" revision, however, to revert to a previous state, let's say the immediate previous state, this revert should be using the "3268b557" revision.

In addition, to the above, a more useful approach could be to allow the user to specify which revision they want to revert to. That would allow it to revert to any state and not only to the immediate state before the current update.
