Overlayfs backend #180

Closed mtelvers closed 3 months ago

mtelvers commented 9 months ago

The PR adds an OverlayFS backend to OBuilder.

OverlayFS is a union filesystem allowing a hierarchy of layers to be stacked on top of any other filesystem. Notable this is useful as TmpFS can be used as the underlying filesystem with a x2 performance improvement over BTRFS on NMVe.
