need to run nfs serive before using unfsd
Works fine until now. Note that both unfs3 and nfs-user-server do not support file locking!
NOTE: I tested on centos 5.6 using unfs3 and I had to run the /etc/init.d/nfs service and see it work before I could use unfs. also use exports -a before using sudo /usr/sbin/unfsd -T -e /etc/exports
