-   - Fail if cache_dir cannot be created from current out_dir
-   - transfer_type_explorers: Explorers are not transferred twice
-   - transfer_type_explorers: No transfer tried if there are no type_explorers

+      -> give ConfigInstall Constructor different manifest
+         -> different manifest is executed.

    - $whatever should fail if there is no global explorer directory
    - emulator may only be called with __ as prefix - fail otherwise!
