This change will let us to have full configuration of a running kernel available in sysctl: sysctl -b kern.conftxt The same configuration is also contained within the kernel image. It can be obtained with: config -x <kernelfile> Current functionality lets you to quickly recover kernel configuration, by simply redirecting output from commands presented above and starting kernel build procedure. "include" statements are also honored, which means options and devices from included files are also included. Please note that comments from configuration files are not preserved by default. In order to preserve them, you can use -C flag for config(8). This will bring configuration file and included files literally; however, redirection to a file no longer works directly.
