Is there anyway to generate a .config file that shows my current kerenel config?

are you talking before you compile the kernel or after? if your talking about before then i dont think so, you have to set the options for the .config to know what you want. you can always try using genkernel.

If you have a current kernel config that you want to save you can:

Todd, the way his question sounds is he wants a .config generated with his specs so he can use it to build a kernel cause he doesnt know what hes supposed to use and remove.

Yes thagame thats is what I want to do.

I tried compiling a kernel with my own settings but its kinda messed up so I want to use the config for my current kernel that I know works when I compile the new one.

ok so if you have a working kernel right now then copy the .config over to the new kernel you want to config and run make menuconfig and it should read the other .config file and your good to go. rememeber if your installing another kernel to change the symlink /usr/src/linux to point to the new kernel folder.

Well, the problem is that i do not have a .config file for my current working kernel. Correct me if i am wrong but wasnt it replaced when I compiled the last kernel ( the one that failed)?

so you dont have a working kernel on your system at all?

yes i have a working 2.4.20 kernel......ok i found it! I was looking in the wrong directory! I was looking for my old config in the directory of my new kernel. Thanks for the help!

Reviving an old thread...

Anybody know how to recover a kernel config file that has been accidentally deleted? Thanks to my fat fingers, the entire kernel source tree for my current kernel went bye-bye. I still have the kernel file itself, and obviously I can recover the rest of the source tree, but that still leaves .config missing. If by any chance someone knows of a way to recover the configuration used to create the running kernel, I'd be appreciative.

Don't remember if this is new in 2.6 or was in 2.4 as well, but if you enabled
[*] Enable access to .config through /proc/config.gz
it shouldn't be a problem.
