Issue body
If the overlay step is re-executed for a part, all layers sitting on top the of layer corresponding to that part need to be repopulated. This process is called "reapplication" of a layer. This is needed to keep the overlayfs stack consistent regarding modified files, including whiteouts and opaque directories.
