Linux Kernel in a Nutshell

Name

IKCONFIG — Kernel .config support

This option enables the complete Linux kernel .config file contents to be saved in the kernel. It documents which kernel options are used in a running kernel or an on-disk kernel. This information can be extracted from the kernel image file with the script scripts/extract-ikconfig and used as input to rebuild the current kernel or to build another kernel. It can also be extracted from a running kernel by reading the file /proc/config.gz.
