Actually, this will be fine for NFSv4 as well as NFSv3 (assuming a V4: line
was added to /etc/exports.
Although exporting the root will be less confusing, any export within a server
file system (such as "/" in this case) will export the entire file system for
NFSv4. (ie. The /usr/src and /usr/ports are referred to as administrative controls
and are only applied by mountd, which NFSv4 doesn't talk to.)

W.r.t. NFSv3 Jason has it completely correct afaik, rick
