Coda Filesystem: kernel module
==============================

We now have a reasonably flexible method to build kernel modules. You
can build the module for a kernel which you are not running at the
time of the build.

To build a custom coda kernel module you need to obtain the tarball
from:

    ftp://ftp.coda.cs.cmu.edu/pub/coda/linux/src/linux-coda-5.2.0.tgz

And follow the instructions in the rest of this file.

NOTE: the code here is always newer than or equal to:
 - the kernel 
 - the big Coda tarball


To build a coda.o module for your Linux kernel:
-----------------------------------------------

For 2.2 kernels:
----------------

A)
In this directory build the coda.o module:

type:
make config  --- answer the questions
make coda.o
su
make install

B)
Get going!  Start Coda.

(venus-setup testserver.coda.cs.cmu.edu 10000 ; venus & )

For 2.0 kernels:
----------------

A)
Prep the kernel

cd /usr/src/linux-for-you
make oldconfig
make dep

B) 
In this directory build the coda.o module:

type:
make config  --- answer the questions
make coda.o
su
make install

C)
Get going!
(venus-setup testserver.coda.cs.cmu.edu 10000 ; venus & )


Note: 
=====

1. If you build for a running kernel, you must still have a source 
tree for that Linux release, otherwise the headers cannot be found.
However, that source tree doesn't need modversions.h etc.

2. We don't actively maintain 2.0 code anymore.  The 2.1 code is
preferred, but not yet perfect.  

Let us know if there are problems!
