Description
We need to provide, in addition to the kernel rpms, also the additional modules that are required
for external users to quickly try our service out.
Namely... we need the AFS module.

Current openafs version in SL5 (slc5-os repo) seems to be 1.4.12.

We should target this version for now.

Some possible instructions here:
http://openafs-wiki.stanford.edu/AFSLore/RpmClientInstallationWithDKMS/
Tried:
# wget http://dl.openafs.org/dl/openafs/1.4.12/openafsrepository-rhel-1.4.12-1.noarch.rpm
# rpm -ivh openafs-repository-rhel-1.4.12-1.noarch.rpm
which required:
# vim /etc/yum.repos.d/openafs.repo
...
baseurl=http://dl.openafs.org/dl/openafs/1.4.12/rhel5/$basearch/
...
but it complains 'missing dependency: openafs-kmod-common'.

Hard, hard...
Right now it the option followed is to take the SLC5 src rpm, like:
http://linuxsoft.cern.ch/cern/slc5X/updates/SRPMS/openafs-1.4.14-0.cern.src.rpm
and try to rebuild it, but it requires not only the kernel-headers, but also the kernel source
(kernel-devel). This is not trivial to generate from the standard kernel make rpm, and a first
naive patch seems to fail to put all required files inside.
Need to investigate better what is in the EL5 kernel spec file and try to do the same to get a
similar kernel-devel rpm.

Done.
Much simpler using the elrepo mainline kernel rpms as a base
- needed to enable NFS4.1 and rebuild, but that's ok as it gives nice -devel and -headers rpms
which then work to rebuild openafs from the src rpm.
This need will go away after this request is fulfilled and we get NFS4.1 enabled in the elrepo
kernel-ml package.
The only issue is that version 1.4.14.x will not work with kernels >=2.6.38, so we had to move
to 1.6.xpre releases (which seem to work fine).
The whole procedure is [documented here|Dpm/Dev/Recipes/KernelAndPNFS].
