SubjectRecovering .config from vmlinuz and System.map
Date
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

+d configs

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 :
