definitelly the kernel implementation cannot manage the loops a re-export
would imply.

yes, you have to run both rpc.mountd and rpc.nfsd with the -r option.I
used this one year ago, and it was really stable with 10 nfs clients
(physicaly the partition was on an AIX server, mounted on a linux server
and then re-exported on many linux clients), but the physical FS status
could not be really coherent in front of what the nfs re-export server
thinks it should be.
