Oops!
I am afraid I remove the line accidentaly. Sorry.

Thanx for the script.
On my test system where NFS server is linux, the first mv back failed.
:::
exporting localhost:/tmp/irush/export
+ mv -v /tmp/irush/nfs/a/b /tmp/irush/nfs/a/c
`/tmp/irush/nfs/a/b' -> `/tmp/irush/nfs/a/c'
mv: cannot move `/tmp/irush/nfs/a/b' to `/tmp/irush/nfs/a/c': Permission denied
:::
Anyway ACL is a good hint actually.
While I cannot reproduce your problem on my side, I'd suggest you to try
a branch attribute "icexsys" for the writable branch such as
# mount -t aufs -o br:$tmp/rw=rw+icexsys:$tmp/nfs=ro aufs $tmp/union
For details, refer to
linux/Documentation/filesystems/aufs/design/xattr.txt and aufs manual in
aufs-util.git.
