What is the "right" way to modify a defconfig file? Most sources I've found just say things like "edit the defconfig file". That seems error-prone -- especially when dealing with settings that have side effects.
I did stumble across one mention of "make savedefconfig", and this seems to be the right way to modify a defconfig file: make myboard_defconfig make menuconfig make savedefconfig cp defconfig configs/myboard_defconfig Do people manually edit their defconfig file when they want to make a change, or do they use "make savedefconfig" like I show above? One reason I'm asking is that the original defconfig file provided by the silicon vendor (Renesas) appears to be a manually stripped-down ..config file, because when I do make vendors_defconfig make savedefconfig The defconfig file generated by 'make savedefconfig' looks _nothing_ like the starting vendors_defconfig. The new defconfig generates the same .config file as the vendors_defconfig file. But the vendors_defconfig file is arranged completely differently with different/extra comments, extra blank lines, etc. -- Grant
