It is not necessary but you'll be starting from scratch. Linux often suggests that's the best thing to do but I've done make oldconfig for 12 years now and never had a problem that I could trace back to using it. It certainly saves time. I also ALWAYS run make menuconfig following make oldconfig mainly so I can exit from menuconfig and get messages (if any) about config problems. Hope this helps, Mark
