Re: Upgrading kernel used in PXE boot

I'm installing FC6 using kickstart from PXE. It works great, and I've used this (and a similar setup with FC2) for years.

Now, I want to use a new kernel during the installation. FC6 comes with 2.6.18-1.2798.fc6, and I want the boot to use some version of 2.6.20 or greater.

What I've been doing is installing with the default kernel, then upgrading to 2.6.20-1.2962.fc6 after the installation is complete. But now I have a need to run 2.6.20 during installation, because of some hardware that's supported in 2.6.20 but not in 2.6.18.

So my question is: How do I create a new initrd.img and vmlinuz (that came in the isolinux directory) to be a new kernel? It's apparently not as simple as copying these files from a running system.

I've spent hours googling. I've seen all sorts of info on adding drivers to initrd.img, but no info on updating the kernel.

Any info would be great!

Hi Eric,

-mandatory note about Fedora Core 6 being End Of Life, you should upgrade or use some Enterprise Linux (derivative)-

you might want to take a look at Revisor. We've been doing successful Fedora Core 6 spins in the past although it really started off with Fedora 7... To indicate what is successful, here's the test matrix that we commonly use (a Fedora 8 version of it):


Revisor you can find in the Fedora repositories (if you run Fedora 7 or 8), and there's a package built for EL5 as well.

See: http://revisor.fedoraunity.org and it's mailing list at http://lists.fedoraunity.org/mailman/listinfo/revisor-users

Kind regards,

Just wanted to mention the different tools

1. revisor by Jeroen Meeuwen
2. pungi by Jessy Keating 3. buildinstall by anaconda team

AFAK they are in that order. (revisor uses pung and pungi uses buildinstall).  I think if you want an easy way to do this your best bet is revisor,  If you want to get into the core of things you might want to give buildinstall a try.  It a very scarry shell script :)

Hope it helps.
