 filename that contains config symbols that the user requires to be
 set to a specific value.  If KCONFIG_ALLCONFIG is used without a
 filename, "make *config" checks for a file named
-"all{yes/mod/no/random}.config" (corresponding to the *config command
+"all{yes/mod/no/def/random}.config" (corresponding to the *config command
 that was used) for symbol values that are to be forced.  If this file
 is not found, it checks for a file named "all.config" to contain forced
 values.
