atomic-unmount - Unmount Images/Containers
atomic unmount [-h|--help] DIRECTORY
atomic unmount will unmount a container/image previously mounted with atomic mount. If the UID of the user is not zero, i.e. if the user is not root, it will expect the image being deleted was mounted by non-root user and will delete the files rather than use the unmount system call.
