Hello everybody,
I installed fc13 (Goddard 2.6.33 kernel). But I needed kernel 2.6.35 so I downloaded kernel-2.6.35.6-43.fc14.src on koji.fedoraproject.org followed the instructions on http://fedoraproject.org/wiki/Docs/CustomKerneland managed to make it works.
However now when I run yum, I get the following warning "kernel-headers-2.6.35.6-43.fc13.i686 is a duplicate with kernel-headers-2.6.33.3-85.fc13.i686"
I guess this is because the installation process ( http://fedoraproject.org/wiki/Docs/CustomKernel)http://fedoraproject.org/wiki/Docs/CustomKernel asked to download kernel-headers-2.6.35.6-43.fc13.i686.
I will have to compile applications in userland that needs the new headers. Can I safely remove the old headers?
Thanks Ryad

Unless you need something from the new ones, you should probably keep the /old/ headers instead, since those are the ones the C library is built against (roughly.) I'm not entirely sure why that wiki page recommends installing new headers, but it probably shouldn't.

The problem is that I need to 1)first patch the kernel 2)then compile some apps in userland with my new patched kernel
My problem is that I do not know what kernel version (old or new) to use for step 1 and step 2.

Indeed, I made a mistake: the new headers are installed at the end of the installation process with (see http://fedoraproject.org/wiki/Docs/CustomKernel): su -c 'rpm -ivh kernel-<version>.<arch>.rpm kernel-firmware-<version>.<arch>.rpm kernel-headers-<version>.<arch>.rpm kernel-devel-<version>.<arch>.rpm'
But still the problem is the same: I need to 1)first patch the kernel 2)then compile some apps in userland
and I do not know what kernel headers version (old or new) to use for step 1 and step 2.

If you don't know what kernel version you need to patch, we certainly won't either. Especially when we have no idea why you need to patch it, or what the patch does.
Also, building applications against kernel headers is a practice that is generally discouraged overall.

Sorry, I was not clear enough: I need to 1)first patch the NEW kernel (to have better time support. I want to add the patch of Alexander Gordeev for better PPS(=Pulse Per Second) support) 2)then compile some apps in userland (mainly pps-tools which is needed by LinuxPPS). Specially the LinuxPPS group say concerning the installation of pps-tools* "Optionally*, when we have older header files, we update the header files using the versions from your new kernel.
$ cd /usr/include $ mv linux linux.old $ mv asm asm.old $ mv asm-generic asm-generic.old $ ln -s /lib/modules/$(uname -r)/build/include/linux linux $ ln -s /lib/modules/$(uname -r)/build/arch/x86/include/asm asm $ ln -s /lib/modules/$(uname -r)/build/include/asm-generic asm-generic"
So may can confirm that I should keep the new headers for step 1 and 2 and reinstall the old one after (as Kyle told me)?

I correct the typo:
