This bug pertains to the RH7.2 Customization Guide
Specifically the section about compiling custom kernels.
http://www.redhat.com/docs/manuals/linux/RHL-7.2-Manual/custom-guide/custom-kernel.html

You should mention that the /usr/src/linux-2.4/configs directory contains the
config files used to build the standard kernels shipped by RedHat. These can be
used as a base for kernel configuration.

For example, you might want a kernel configured the same as the standard i686
kernel, except that you want ntfs enabled as a module. To make this
configuration, you would: 
% cp configs/kernel-2.4.9-i386.config .config
% make xconfig
and in the xconfig program, make only the desired change, and save&exit.
(And of course, proceed with the kernel compilation).
