History
Tim J. Robbins d14e51c95c Add support for the Coda 6.x venus<->kernel interface. This extends 
FIDs to be 128-bits wide and adds support for realms.

Add a new CODA_COMPAT_5 option, which requests support for the old
Coda 5.x interface instead of the new one.

Create a new coda5.ko module that supports the 5.x interface, and make
the existing coda.ko module use the new 6.x interface. These modules
cannot both be loaded at the same time.

Obtained from:	Jan Harkes & the coda-6.0.2 distribution,
		NetBSD (drochner) (CODA_COMPAT_5 option).

                Announcing the Availability of the
                        Coda Distributed
                           Filesystem
                              for
                         BSD Unix Systems

        Coda is a distributed filesystem like NFS and AFS.  It is
freely available, like NFS.  But it functions much like AFS in being a
"stateful" filesystem.  Coda and AFS cache files on your local
machine to improve performance.  But Coda goes a step further than AFS
by letting you access the cached files when there is no available
network, viz. disconnected laptops and network outages.  In Coda, both
the client and server are outside the kernel which makes them easier
to experiment with.

To get more information on Coda, I would like to refer people to
        http://www.coda.cs.cmu.edu
There is a wealth of documents, papers, and theses there.  There is
also a good introduction to the Coda File System in
        http://www.coda.cs.cmu.edu/ljpaper/lj.html

Coda was originally developed as an academic prototype/testbed.  It is
being polished and rewritten where necessary.  Coda is a work in
progress and does have bugs.  It is, though, very usable.  Our
interest is in making Coda available to as many people as possible and
to have Coda evolve and flourish.

The bulk of the Coda filesystem code supports the Coda client
program, the Coda server program and the utilities needed by both.
All these programs are unix programs and can run equally well on any
Unix platform.  Our main development thrust is improving these
programs.  There is a small part of Coda that deals with the kernel to
filesystem interface.  This code is OS specific (but should not be
platform specific).

Coda is currently available for several OS's and platforms:
        Freebsd-2.2.5: i386
        Freebsd-2.2.6: i386
	Freebsd -current: i386
        linux 2.0: i386 & sparc
        linux 2.1: i386 & sparc
        NetBSD 1.3: i386
	NetBSD -current: i386
The relevant sources, binaries, and docs can be found in
        ftp://ftp.coda.cs.cmu.edu/pub/coda/

We intend to come out with new Coda releases often, not daily.  We
don't want to slight any OS/platform not mentioned above.  We are just
limited in our resources as to what we can support internally.  We
will be happy to integrate OpenBSD support as well as other OS
support.  Also, adding platform support should be relatively easy and
we can discuss this.  The only difficulty is that Coda has a light weight
process package.  It does some manipulations in assembler which would
have to be redone for a different platform.

There are several mailing lists @coda.cs.cmu.edu that discuss coda:
coda-announce and linux-coda.  We are going to revise linux-coda to be
OS neutral, since it is mainly Coda we want to discuss.  We appreciate
comments, feedback, bug reports, bug fixes, enhancements, etc.
