    "make *config" checks for a file named "all{yes/mod/no/random}.config"
    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.

         NOTES on "make config":
         - having unnecessary drivers will make the kernel bigger, and can
