How about patching the /etc/rc.d/nfsd script like this:


[..]
nfsd_precmd()
{
                if checkyesno nfs_server_newnfs_only; then
                        echo 'NFS server serving only newnfs (NFSv4)=YES'
                        sysctl vfs.newnfs.server_min_nfsvers=4 > /dev/null
                fi
[..]

It checks if there is a 
nfs_server_newnfs_only=YES 
set in rc.conf, and if so, it runs the sysctl command.

But, after testing, it is too late (nfsd starts with NFSv3 support). Any idea where to put that patch  ?
