I need an implementation (and interface) that can be used at the beginning of the diskToMirror process (!!!! before starting the local cache) and that would extract each part of the tar.gz to its location:

• docker/v2/repositories => local registry cache storage
• docker/v2/blobs/sha256 => local registry cache storage
• working-dir => working-dir folder
• hidden history file => under working-dir
• image set config => under wokring-dir
