How can I get the running kernel's .config

Hi there,
I oh so cleverly cleaned my /usr/src/linux/ dir, so I dont have my last built config.
I also don't have .config support enabled in the old kernel - how can i recompile my new kernel with the old config?

Thanks in advance,
Cheers,
Serrix

Since he use make menuconfig, maybe he doesn't copy is .config in /boot.

This .config doesn't appear by magic in /boot for my concern when you compile your kernel.

Your right, all i have in /boot/ is the kernel (bzImage) itself...
Any other ideas? Thanks for the ones already given too.

hmmm, it SEEMS to have worked, just by loading the old kernel and doing a make oldconfig from /usr/src/linux.

Thanks for your help, i'll let you know if i'm wrong and it didn't work but so far it looks good

And after doing it, you make a copy in /boot, like config-2.6.22-gentoo-r8.config

With that, you will have a copy of your .config.

Hi,

you can also use the file /proc/config.gz. This should be your running kernel's config. gunzip it, alter the access rights if needed and copy it to /usr/src/linux/

hallo,

i always do :

make && make modules_install && cp arch/i386/boot/bzImage /boot/vmlinuz-2.6.22-gentoo-r10-2 && cp .config /boot/config-2.6.22-gentoo-r10-2

when compile the kernel
