If this environment variable is not set, the diskless root fs will use NFSv2 and the same defaults as before. This fixes the problem where the diskless nfs root fs had to be on a FreeBSD server for NFSv3 to work, because it did not know the correct file handle length and assumed the size used by FreeBSD. END
