Binary package “unfs3” in ubuntu maverick

User-space NFSv3 Server

 UNFS3 is a user-space implementation of the NFSv3 server specification. It
 provides a daemon for the MOUNT and NFS protocols, which are used by NFS
 clients for accessing files on the server.
 .
 Unlike nfs-user-server, unfs3 is capable of handling files larger than 2GB, but
 there is currently no support for file locking.
