We just hard code "fsid=12345" into the /etc/exports for each mountpoint on the "re-export" server. We use config management on our servers to maintain consistency. We also mostly use NFSv3 re-exports but that shouldn't matter much. Things get a bit trickier in the case of something like a Netapp that might have multiple "volumes" appear as a single namespace (you have to fsid each one in the tree).
