The idea of checking in the Unix filesystem first is for development
purposes (both for us for users) when developing add-ons, like skins, so
you can directly work on the file without having to create an archive
first. Just save the file in your editor and restart the game.

What I want is simple overriding of mounts. Look in the most recently
mounted archive, then the next most recently and so on. Optionally, look
in the Unix filesystem before anything or as a last resort.
