Ok, so the scenario is similar to this case without aufs.
NFS CLIENT
- mkdir dirA
- cd dirA
- touch foo NFS SERVER
- mv dirA dirB
- cp -pr dirB dirA
- rm -fr dirB
- getcwd(2) in ls(1)
--> ESTALE Bang!
This looks like an NFS natural behaviour.
Hmm, I have to think more in order to make NFS server to address this
case. But it might be impossible.
