Visible whiteouts? Sounds like philosophy. :-) I don't think it is a good idea introducing a new option. If you can,,, - modify AUFS_WH_PFX in include/linux/aufs_type.h - build another aufs module named 'visible-whiteout' for instance, you may need to modify some other symbols in order to stop conflicing with the symbols in original aufs. - mount layer1=ro+wh:layer2=ro+wh as 'visible-whiteout' filesystem-type then you will get what you want, I guess. But, in squashfs world, it is easier to execute mksquashfs and append the contents of layer1 to the layer2 image.
