+ Announcing the Availability of the
+ Coda Distributed
+ Filesystem
+ for
+ BSD Unix Systems
+
+ Coda is a distributed file system like NFS and AFS. It is
+freely available, like NFS. But it functions much like AFS in being a
+"stateful" file system. 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, 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 file system 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
+file system 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 wish 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 is relatively easy and we can
+discuss this. The only problem 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.
