   - This module has two possible ways of operation.
-  - If 7zip is installed on the system, this module extracts files from an ISO

-    if needed.
-  - If the user has mount-capabilities (CAP_SYS_ADMIN on Linux) this module
-    mounts the ISO image to a temporary location, and copies files to a given
