[Centos] 2.6 kernel on CentOS-3.3

Hi

I am happy to share a "proof of concept" for a centos-3.3 (not yet 3.4 ready)
x86 and x86_64 distributions running either 2.4 and 2.6 linux kernels.

This is not an official statement of the CentOS team!

<include std disclaimer>
don't complain if this howto eats your machine ;)
It works for me and the src.rpm are provided.

In order to have a 2.6 kernel on CentOS-3, one need to 
upgrade a few packages: at least module-init-tools, sysstat, initscripts...
But in order to keep a 2.4 kernel happy, you must keep modutils around.

I have repacked both modutils AND module-init-tools in the
same package and it is providing both.

mkinitrd needs to copy both insmod(module-init-tools) and insmod.old
(modutils) into your initrd, since you can use either 2.4 or 2.6 kernel.

the initscripts_26 is trying to get the initialisation for both series
(there is much room for improvememt).

A prebuild linux 2.6.10-ac8 kernel is there too, but you don't need it, since
you can compile your own. I did not make a mandatory requirement for such a
package.

/etc/modprobe.conf is autogenerated, but some modules
could have changed name, so have a look at it!

all the files are here:
ftp://ftp.pasteur.fr/pub/BIS/tru/2.6_CentOS-3/yum

</blurb>

<howto>
1) wget ftp://ftp.pasteur.fr/pub/BIS/tru/2.6_CentOS-3/yum.conf.mini

use sudo or become root
2) yum -c yum.conf.mini -y update
3) yum -c yum.conf.mini -y  install initscripts_26

either install you own linux-2.6.x kernel
or
4a)  yum -c yum.conf.mini -y  install linux linux-doc
4b)  yum -c yum.conf.mini -y  install linux-smp
4c)  yum -c yum.conf.mini -y  install linux-source

reboot

- linux src.rpm is a steal for the cAos-2 + update to 2.6.10-ac8
