Note: the book by Greg Kroah-Hartman "Linux Kernel in a Nutshell" see Resources will be referenced, quoted and paraphrased frequently in this section. It will be referred to as "gkh-lkn". Graphical menu using Qt5.

Graphical menu using GTK. Review changes between kernel versions and update to create a new. Generates a new configuration with default values from the ARCH supplied defconfig file while, at the same time, maintaining all the previous options set in the. This is a fast and safe method for upgrading a config file that has all the configuration options it needs for hardware support while at the same time gaining bug fixes and security patches.

Enables all configuration options in the kernel. Make sure a backup of the current kernel configuration is acquired before using this option! Options in square brackets can be activated or deactivated. The asterisk marks the menu entry as activated. The value can be changed with the space key. It is also possible to press Y key Y es to activate or N key N o to deactivate the selected entry.

Options in angle brackets can be activated or deactivated, but also activated as module indicated by a M. Options in curly brackets can be activated or activated as module but not be deactivated.

There is no choice. Manual configuration is explained as the default choice since it is the best way to optimize an environment.

A full listing with description is available at the Kernel overview page. Choose an appropriate kernel source and install it using emerge :. However, this symbolic link will not be created by default. An easy way to create the symbolic link is to utilize eselect's kernel module. In order to create a symbolic link called linux , use:.

However, one thing is true: it is vital to know the system when a kernel is configured manually. Another source of system information is to run lsmod to see what kernel modules the installation CD uses as it might provide a nice hint on what to enable.

Now go to the kernel source directory and execute make menuconfig. This will fire up menu-driven configuration screen. The Linux kernel configuration has many, many sections.

Enabling support is possible, but goes beyond the scope of the handbook. Make sure that every driver that is vital to the booting of the system such as SCSI controller, etc. Next select the exact processor type. It is also recommended to enable MCE features if available so that users are able to be notified of any hardware problems. Now go to File Systems and select support for the filesystems that will be used by the system.
