I was just wondering if there was a program out there that would generate a menuconfig file based on what your system was running (modules and stuff like that) for kernel customization out there? If there isn't is there a way I can find this information about by digging around my system?

I would like to make a custom kernel that can still allow my system to function like it is right now, but be as small as possible. Also, unlike what my profiles says this will be for a Slackware box (don't think that will much matter).

Thanks in advance

I don't think that there are any programs that will autoconfigure your kernel. Pretty much the best way to get as small a kernel as you can is to go through all the options and cut out the stuff you know you don't need.
