If we have a choice then the choice is represented by a symbol. symbol->def[S_DEF_USER] is set to the selected symbol. If we read all the choice values then we set: symbol->flags |= SYMBOL_DEF_USER If we have a choice where we do not have all choice_values which is the case with the minimal defconfig then the missing choice_value results in that SYMBOL_DEF_USER is not set. [See confdata:conf_read after the sym_ok label] Later in symbol.c:sym_calc_value the visibility is set to mod if we do not have all values. And therefore the coice value is set to m not y. I will look a bit more at it tonight.
