     196== Kernel Configuration
     197If you are using buildroot to build a kernel {{{BR2_KERNEL}}}, you can choose where to get the kernel config (the in-kernel arch default, another in-kernel defconfig, or a custom kernel defconfig). Regardless of your initial kernel config choice you can later modify the kernel configuration via {{{make linux-menuconfig}}}. Following that you can use {{{make linux-savedefconfig}}} to create a defconfig file in the Linux build directory and {{{make linux-update-defconfig}}} to save the Linux defconfig to the path specified by {{{BR2_LINUX_KERNEL_CUSTOM_CONFIG_FILE}}}.
