[OpenAFS] scripts to install openafs

[Jeff Blaine]

Here's what we do, for what it's worth.

It's been working excellent for us so far.  Note that although
we run cfengine on clients ("Managed"), we have to cater to
non-Managed hosts which want a way to get AFS, so using
cfengine to manage our AFS installs/file-copies is not
possible.

We store things in NFS:

                        |-1.4.11---|-32-
                        |          |-64-
                        |
                        |-1.4.12.1-|-32-
|-linux-kernel-modules-|          |-64-
                        |
                        |-1.4.5----|-32-
                        |          |-64-
                        |
                        |-1.4.6----|-32-
                        |          |-64-
                        |
                        |-1.4.7----|-32-
                                   |-64-


                           |-amd64_linux26-|-C-------
|-production-linux-client-|               |-modload-
                           |
                           |-i386_linux26--|-C-------
                                           |-modload-

|-production-solaris-client-|-sun4x_510-|-C-------

Bootstrap via init script which runs before rc3.d/S90afs
grabs what it needs from the NFS area in order to match
our desired OpenAFS client specs.

No more surprises due to kernel updates = no working AFS
at reboot.

cfengine2 runs every 30 minutes via cron in our environment.
When we need to populate our repository of kernel modules
(in order to change OpenAFS revs), we temporarily add a
"build and gather modules" script call to our "30-minute"
cfengine config file.  It builds OpenAFS on all of our
boxes and drops kernel modules into NFS space.
