That's not exactly what I said :)

With old NFS versions (2/3), the server exports an actual filesystem 
(/home, for instance), which is seen directly by clients with its actual 
path (/home, here).

With NFSv4, the server remaps its actual filesystem (/home, for 
instance) in a pseudo-filesystem, which is seen by clients as a root 
filesystem (/ here). Consider it as some kind of implicit chroot.

With earlier implementations, you had to explicitely mark one of the 
filesystem as the root one, and make sure every other filesystem was 
reachable from it, using bind mount if needed. You've got some more 
detailed explanations here:

According to official NFS wiki, it seems this is no longer needed, and 
than the implementation handle it automagically for you:

Well, you'd better check if you're actually using NFSv4, and not a older 
version, if you want optimal performances.
