       lnfs - long name file system

       lnfs [ -r ] [ -s srvname ] mountpoint
       unlnfs mountpoint

       Lnfs  starts  a process that mounts itself (see bind(2)) on mountpoint.
       It presents a filtered view of the files under the mount point,  allow‐
       ing  users  to  use long file names on file servers that do not support
       file names longer than 27 bytes.

       The names used in the underlying file system are the base32 encoding of
       the  md5 hash of the longer file name.  The user need not know the map‐
       ping since lnfs does all the work.  Lnfs maintains a file .longnames in
       the directory mountpoint to record the long file names.

       The options are:

       -r     allow only read access to the file system

       -s     provide  a service name, srvname, to post in /srv.  Without this
              option, no posting is performed.

       Unlnfs renames files with shortened names to their actual  long  names.
       It  is  useful once you have moved to a file server with true long name




       This exists only to shame us into getting a real long name file  server
