Duplicate kernel-headers after upgrading to 2.6.35

[Ryad Ben-El-Kezadri]

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)?
