    type: filesystem_unified

    # The path where items should be mounted (comparable to mount points in
    # Unix-like systems). This is “/” by default, meaning that items will have
    # “/” prefixed to their identifiers. If the items root were “/en/”
    # instead, an item at content/about.html would have an identifier of
    # “/en/about/” instead of just “/about/”.

    # The path where layouts should be mounted. The layouts root behaves the
    # same as the items root, but applies to layouts rather than items.
