Here is the pertinent part of the mountd man page under Linux: -r or --re-export Allow imported NFS file-systems to be exported. This can be used to turn a machine into an NFS mul- tiplier. Caution should be used when re-exporting loopback NFS mounts because re-entering the mount point will result in deadlock between the NFS client and the NFS server. a1 http://underground.org/
