Mike, Charles is correct on this. As installed there is no ".config"
file in /usr/src/linux. After a "make --oldconfig" you'll have a copy
of the one that was used to build the installed kernel.
Depending on what you change, you may need to type "make --oldconfig"
again, as I recall. What I generally do is the following:
make --oldconfig
-- this gives me the copy of the original .config file. I believe it's
-- copied from /usr/src/linux/configs if there's no existing .config.
-- now I edit and set raid to "n", Frame Buffering, if necessary, etc.
make --oldconfig
-- since there is an existing .config file in /usr/src/linux, it runs
-- through that. What this does is to clean out any inconsistencies
-- in the .config file. As an example, if you turn off Frame Buffering
-- it would still build a number of modules if you didn't rerun make
-- with the "--oldconfig" option. Check afterwards in your new .config
-- and you'll find that the dependent modules on what you have switched
-- off will no longer be there.
then just complete the process with
make dep
make clean
make bzImage
make modules
make modules_install
and then install the new kernel, which is in a ./arch subdirectory.
