apport does not find anything of relevance. I am using Ubuntu Server 12.10 amd64, with standard kernel, aufs and nfs packages. I have confirmed that CONFIG_AUFS_EXPORT appears to be disabled both in the distributed kernel and in the Ubuntu Kernel git HEAD. This flag is documented as a requirement for NFS exports in http://aufs.sourceforge.net/aufs3/man.html.
