Now, let's take a look at the various kernel configuration option categories. I'll include a brief overview of each category below. I encourage you to follow along by typing "make menuconfig" or "make xconfig" in /usr/src/linux.

Code maturity level options: This configuration category contains a single option: "Prompt for development and/or incomplete code/drivers." If enabled, many options that are considered experimental (such as ReiserFS, devfs, and others) will be visible under other category menus. If this option isn't selected, the only options that will be visible will be those that are considered "stable." Generally, it's a good idea to enable this option so that you can see all that the kernel has to offer.
