installed kernel configuration

[Kevin Brown]

or do what I do.  Get the src.rpm of the kernels from Redhat.  install it (rpm
-ivh kernel*.src.rpm), then go to /usr/src/redhat/SOURCES and look for the
config files there.  They are usually named kernel-<version>-<proc type>-<build
type>.config.

e.g. kernel-2.4.18-i686-enterprise.config

copy that to /usr/src/linux/.config

Now you have the config that redhat used.

The only way that "make oldconfig" works is if you get the kernel source by installing the "kernel-source" (and maybe the "kernel-headers") RPMs (note: not the "kernel" SRPMs) from RedHat. Using the kernel sources from www.kernel.org, as I originally suggested, will not work.
