Default configurations, as per "make savedefconfig", only record differences to the default. There will be no "CONFIG_NET=y" in a defconfig if "select NET" configures it automatically. This is per design to reduce the size of the configuration file. On the downside, it means that a "simple" change such as "select NET" -> "depends NET" has far reaching consequences. Guenter
