 If you wish to modify a file simply provide your version of it in your overlay and it will be copied over the original. If you wish to remove a file you can provide a 0-byte version of the file which may meet your needs.
 
+Additionally you can use {{{BR2_ROOTFS_POST_BUILD_SCRIPT}}} to make any changes after buildroot builds but before the rootfs images are assembled.

+== Kernel Configuration
+If 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}}}.
