Bug Description

Overlayfs handles multiple layers in a different manner and limits layer count. Need to suport that.

The newer overlayfs implementations support direct mounting of multiple lower read-only layers via a colon (:) separated list in lowerdir= specifier. We need to prepare a list for this and try it before the current multiple overlaid mounts mode which is currently limited to two layers.
