-Our current recommendation is to use Inferno (http://www.vitanuova.com/inferno)
-as the 9p server.  You can start a 9p server under Inferno by issuing the
-following command:
-   ; styxlisten -A tcp!*!564 export '#U*'
-
-The -A specifies an unauthenticated export.  The 564 is the port # (you may
-have to choose a higher port number if running as a normal user).  The '#U*'
-specifies exporting the root of the Linux name space.  You may specify a
-subset of the namespace by extending the path: '#U*'/tmp would just export
-/tmp.  For more information, see the Inferno manual pages covering styxlisten
-and export.
-
-A Linux version of the 9p server is now maintained under the npfs project
-on sourceforge (http://sourceforge.net/projects/npfs).  There is also a
-more stable single-threaded version of the server (named spfs) available from
-the same CVS repository.
