It's even funkier, since you said an 8.0 system, it should be nfsv4. Rick
Maklem may be interested in your findings, on either freebsd-fs or in light
of the upcoming release on freebsd-current.
This is also a nice dilemma: nfsv4 is still wet behind the ears, but v2
should be considered deprecated. But - it is good to know that with all
the new NFS code in 8.0, the v2 compat plays nice with Solaris v2.
