    Finding kernel compilation options

    I successfully compiled my first kernel a couple of days ago (I'm building LFS), but wasn't 100% sure exactly which options I should choose from the compilation menu. Now that I am becoming more familiar with the options I should have chosen I would like to find out if I actually included them. Is there a way I can examine the compiled kernel to see what I included, or is the only way to recompile with the correct options chosen??

    Hm.. do you still have the kernel sources you used for that specific kernel? If so, go to that dir and view the ".config" file (with a dot, yes, that's because it's a hidden file).

    On 2.6 kernels, there's an option that it puts the kernel config file in /proc/config.gz or something like that.

    It was a 2.6 kernel, but it didn't put anything into /proc, and I couldn't find *config.gz* anywhere on my drive.
    All is good though, cos I found the .config file in the sources directory.

    Thanks for your help.

    You'll need to compile the kernel with CONFIG_IKCONFIG_PROC support for it to put config.gz in /proc.
