Thanks for your patch, which is now commit 6ded8a28ed80e4cc ("bootconfig: Default BOOT_CONFIG_FORCE to y if BOOT_CONFIG_EMBED"). After this change, an all{mod,yes}config kernel has: CONFIG_BOOT_CONFIG_FORCE=y CONFIG_BOOT_CONFIG_EMBED=y CONFIG_BOOT_CONFIG_EMBED_FILE="" Will this actually work? I haven't tried booting such a kernel yet.
