I guess it was just because the mount point is same to the RO branch (./rodir). You need to run "mount -B" _after_ mounting aufs, but you cannot refer to the RO branch "rodir" directly anymore. It is covered by aufs "rodir". Try something like this (I didn't try by myself though). # mount -t aufs -o airs=./rwdir=rw:./rodir=ro none ./rodir.tmp # mount -B ./rodir/exfile ./rodir.tmp/exfile # mount -M ./rodir.tmp ./rodir J.
