Let me make sure. Do you mean something like this? # mount -t ubifs -o rw /dev/brabra /mnt # ls -al /mnt (no error) # mkdir /mnt/.wh.dir # ls -al /mnt (no error, .wh.dir appears) # mount -o remount,ro /mnt # ls -al /mnt (error, .wh.dir doesn't appear) The dir .wh..wh.plnk is a hidden dir to handle the aufs internal "pseudo-link" which is maintained at remount/umount time by aufs2-util.
