3.8 mountd -n

[Will H. Backman]

Trying to get OS X to mount an openbsd nfs share.  I can force OS X to 
use reserved ports by using "mount_nfs -P" from the command line, but 
users mounting from the finder don't have that option.
OpenBSD man page for mountd says that there is an -n option to allow 
mounting from unreserved ports, but running mountd with that option 
doesn't seem to make a difference.   Any ideas?
Also, if this flag worked, I'm not sure how one would put it in 
/etc/rc.conf.local

Thanks in advance.
