Eric,
you are a genius !!! I should have noticed the relative size of the 
2.6.9 kernel and what I thought was a patch file : 35 MB !!! :)

I feel idiot !

Of course.

Yes this is very clear and I know.

The cp -rl does something a little different.
In this way you leave your original tree intact, create a new source 
tree made of hard links therefore not really "copying" anything, but 
when you patch the patched files will live only in the new tree so that 
you will have two different source trees with only the needed hard disk 
space overhead.

Thank you so much and have a great day.
