    Question Use 2.6.x .config file for 3.8.x kernel compilation

    Hey everyone, quick question here. Can I use a config file from a version 2.6.x kernel that is on a RHEL system and run make oldconfig and end up using the translated config file to compile a version 3.8.x kernel that will run on Ubuntu? (I would also run make menuconfig and go through those motions too.) Is there any reason that a .confile file from 2.6 would be too far away from a 3.8 kernel to translate properly?

    In theory, it should work and ignore whatever has been added since 2.6 but in reality, I don't know of a soul, except for perhaps Linus himself, who could answer your question with any degree of certainty. I'd go for it, and see what happens. It might just work out. Good luck!

    LOL. OK. I knew it was kind of a longshot. I will run make oldconfig so that should update the old config file with all the new stuff, right? I'll post my results here after I try this. Thanks!

    I just wanted to share with everyone that this worked! I took the 2.6.x config file and ran make oldconfig and chose the defaults for all new features, and then used the new file to compile a version 3.8.1 kernel. The new kernel was used to boot a server that had a very specific and uncommon RAID card. Only one version of Linux worked with that hardware and that was using a distribution that used the 2.6 kernel but I wanted to run a different distribution on it with a 3.8 kernel. Since the 2.6 distribution worked I knew that that config file had the correct options set; thus the reason for using that config file as a template for the 3.8 one. Thanks for your feedback about this!
