Is it possible to use an NFS export as the lower layer on Overlayfs? 2. If 1 is not possible in the current release, what's needed to do this? 3. Are whiteouts configurable? That is if a file is deleted in the upper layer, can Ocerlay fs revert to thefile of the same name in the lower layer? Duncan
