Is there a .config for each kernel image? I wanted to see if there was a way I could use make menuconfig on my current one to see how it's set up.

Yes there is. I'm assuming you're still on Ubuntu.

Open a terminal and type this:

ls /boot/config-`uname -r`

You can cd to /boot and see that there is a corresponding config file for each installed kernel. the command embedded in the backticks returns the current running kernel's name.

To build a kernel with the options & modules in the currently running kernel-image you would run `make oldconfig` after placing the /boot/config`uname -r` file in your /usr/src/linux directory (after getting the kernel sources).

I hope that makes some sense. Here's a great how-to page for compiling your kernel the Debian way using the pristine sources from kernel.org:

I usually just grab the linux-source package using apt-get.
