Thanks Stefan,

That makes more sense to me than what I have found so far. But if I need 
to compile a kernel module for the 3.13.0-33-generic kernel image, then 
I assume I have to change the Makefile version, such as EXTRAVERSION, 
etc? Because if I use the config file, found in /boot, then I end up 
with a kernel version (uname -a) equal to the upstream stable version 
which is the base for this kernel.

I was expecting that the Ubuntu kernel sources would generate the exact 
same kernel image (including the kernel version) as can be found in one 
of the images.

Wim.
