Why not just use Jaunty's kernel?

$ uname -r
2.6.28-11-generic

$ cat /proc/fs/lustre/version 
lustre: 1.8.1.50
kernel: patchless_client
build:  b1_8-20090921170221-CHANGED-2.6.28-11-generic

Ahhhh.  You really want to be using b1_8 for this.  1.8.1[.x] doesn't
have the required kernel support.  Certainly you could find the relevant
bugs in bugzilla and do some backporting but it might be a bit of work.

Additionally, b1_8 (aka 1.8.2) also has debian packaging support (on an
unsupported basis at this point) in /debian.  Here are the installed
packages, built from the /debian in b1_8 from my client:

ii  lustre-client-modules-2.6.28-11-generic    1.8.1.50-2   Lustre Linux kernel module (kernel 2.6.28-11
ii  lustre-tests                               1.8.1.50-2   Test suite for the Lustre filesystem
ii  lustre-utils                               1.8.1.50-2   Userspace utilities for the Lustre filesyste

Yes.  With the Jaunty kernel even.

You really don't want to be messing around with HEAD for anything other
than previewing technology.  Certainly not for a production system.
b1_8 is the branch you are really looking for.
