Similar to the Config-Environment which stores compile options to build FRITZ!OS the Kernel-Config stores compile options to build the respective Kernel. Unlike the Config-Environment which is accessible as shell variables there is no direct way to access the Kernel-Config. However, there's a nice mechanism called IKCONFIG (Included Kernel-Config, CONFIG_IKCONFIG)[1] which permits to embed the compressed Kernel-Config in the kernel binary. IKCONFIG can be located in the decompressed kernel binary by its signatures and can be accessed from the running kernel at /proc/config.gz, if CONFIG_IKCONFIG_PROC is enabled. Unfortunately AVM only uses this feature for nearly 40 models. Thanks! Enough to create this section, but not representing all current Box-Models.

Dear AVM: Please activate CONFIG_IKCONFIG for all kernels and modules.builtin (ascii) in rootfs to help developers. Thanks!
