Hi, For several years I've used a trick to be able to maintain a simple defconfig that works across many versions, and requires little maintenance from my part: % cat arch/x86/configs/x86_64_defconfig ~/my-config > .config && make olddefconfig I'm sending a proposal to integrate it on the build system so that many people can do the same in a simple manner. The interesting part is how to generate this simplified defconfig. In a nutshell; you want to take your .config, remove everything that is the default in the Kconfig files (what savedefconfig does), but also removes anything that is in the default defconfig (e.g. x86_64_defconfig) I've been doing this by hand, but today I gave it a shot to automate this. The result is a bit crude, but it works. Thoughts?
