My kernel configuration have CONFIG_IKCONFIG=y but I often copy the config from the latter instead, since I booted with arbitrary kernel version when compiling two or three versions, and I want to ensure that the config used is from correct version (i.e. I use /boot/config-5.15.x-string to build 5.15.x+1 kernel).
