I believe that these do what you are asking about. If not, please provide your example that is not working. Or: this one works for me: --- init/Kconfig | 4 ++++ 1 file changed, 4 insertions(+) --- linux-next-20181114.orig/init/Kconfig +++ linux-next-20181114/init/Kconfig @@ -1858,6 +1858,10 @@ config CMDLINE endif +config SPECIAL_STRING + string + default "special" + endmenu # General setup source "arch/Kconfig" and "make oldconfig" gives me a .config file that contains: CONFIG_SPECIAL_STRING="special" HTH. or ask more questions... -- ~Randy
