Hello,
I've a box running a linux 2.4.18-14 (RH stuff), for which I've lost
the .config file...
I've gone through a long .config recovery process by looking at the
entries in System.map, changing the configuration, building the kernel,
diffing the new System.map with the reference one, again and again.
The diff process was done only on the symbol names and the last diff
states :
diff -urN System.map-9 System.map-2.4.18-sound | less
--- System.map-9 Tue Feb 18 13:36:33 2003
+++ System.map-2.4.18-sound Tue Feb 18 09:47:47 2003

Could someone direct me to where is located this "configs" stuff
that I can't find ?
Second question : the addresses in front of the symbols don't match
(except for the first ones)... I'm using the same kernel tree, the
same compiler... Any idea ? First diff is :

I wrote an optional feature that stores kernel .config info inside
the 'vmlinux' file in an array named 'configs'. I don't know if
it's included in your kernel or not.
Some patches for this in-kernel-config feature are available at
http://www.osdl.org/archive/rddunlap/patches/ikconfig/
and it's in Alan Cox's 2.4.-recent patches.

Hello Randy,
Not sure if it's your patch that RH has included, but that was it,
the .config stuff in the kernel...
Thanks very much !

Paul
