LNFS(4) LNFS(4)
NAME
lnfs, relnfs, unlnfs - long name file system
SYNOPSIS
lnfs [ -fr ] [ -l maxlen ] [ -s srvname ] mountpoint
relnfs [ -f ][ -l maxlen ]
unlnfs mountpoint
DESCRIPTION
Lnfs starts a process that mounts itself (see bind(2)) on
mountpoint. It presents a filtered view of the files under
the mount point, allowing users to use long file names, or
file names with spaces on file servers not supporting
either. The default maximum file length is 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 mapping since lnfs does all the work.
Lnfs maintains a file .longnames in the directory mountpoint
to record the long file names.
The options are:
-f the underlying file system allows spaces.
-m maxlen
set the maximum file length allowed.
-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 support. Relnfs changes the max-
imum file length or support for spaces in file names in the
underlying file system.

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