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.

** Summary changed:

- casper: need to handle multiple layers differently for later kernels
+ casper: need to handle multiple overlayfs layers differently for later kernels

** Changed in: casper (Ubuntu)
