RhodeCode Control

Per documentation, restoring an instance involves creating a new instance and replacing files.
Assuming one is restoring their entire ~/.rccontrol folder, the issue, as I see it, comes down to not having the required files expanded under the NIX store, as symlinked from instancename/profile.
I'd like to suggest an rccontrol extract command that downloads (if not in cache/offline) and extracts the proper files on restore/upgrade, without the intermediary new instance step.
This would also simplify cleanup of the nix store on live instances.
