Hello, dear community, I want to ask what is a proper way to disable config forcibly. For example, I have some config somewhere in common Kconfig: config NAME bool "some short description" if EXPERT default y When I do the command `make olddefconfig`, it will generate a new config based on old .config. So my expectation was if I put CONFIG_NAME=n to .config and then ran the command, I'll get CONFIG_NAME=n in the final .config, but it doesn't work. If you update 'config NAME' from `default y` to `default n`, all will be fine, but it is not the best solution to touch common Kconfig. If you use 'make defconfig' and put `# CONFIG_NAME is not set`, then all will be fine too, but my CI uses 'make olddefconfig`, which ignores `*_defconfig`. Also, I tried to override CONFIG_NAME in arch-specific Kconfig in the following way: config NAME bool default n and it works for olddefconfig, but if you use `make randconfig`, it still can set CONFIG_NAME=y. I tried debugging the conf utility and found that [1] CONFIG_NAME is set to n, but [2] it takes `default y` from the original in Kconfig common, ignoring what I write to .config. Is it expected behavior? Could you please let me know the right solution?
