[ILUG] Kernel Question

I discovered the extract-ikconfig script in the scripts directory however 
as you rightly pointed out it is not implemented in 2.4 kernels.
I ran it against my kernel 2.4.26 which gave no output (as the config file 
had not been placed in the kernel).

My main issue is that module symbols will be generated differently when 
config file is missing an option which is compiled into the kernel. I am 
trying to compile in the mp-pppe  module for a VPN connection. The kernel 
is on a production system and recompiling the whole kernel without the 
original config file is not an option. I reckon i will have to guess my 
config until modules do not give module dependency failures when running 
depmod against them.

Lesson always backup your .config file
