Automating the kernel emerge, eselect, compile, configuration copying and detection, hardware detection install, etc along with grub configuration updating to save some effort when installing, upgrading, or trying a new kernel.

• A selection of kernels including gentoo-sources, hardened-sources, vanilla-sources, pf-sources, etc
• The option to unmask testing versions of your selected kernel
• Handles the eselect kernel set by giving a list of installed kernels to select in an easy manner
• If dependencies are not installed, you are prompted for the script to install them
• The option to copy a kernel .config from the scripts running directory to the selected kernels location or using the kernel from the running system
• Makes use of kergen for enabling hardware support for the currently running system in the selected kernel
• Options of compiling the kernel with the regular make method, Sakakis build kernel script, or Genkernel
• In all compiling methods, you are given the amount of CPU cores available and prompted to select how many to use
• In the regular make method and Genkernel selections you are given the option of using menuconfig or gconfig for kernel customization
• Supports updating your GRUB config. If GRUB is not installed it will be, walking you through configuration by prompting which disk to install to, etc.
• Among other nifty features..

Note: Kernel compilation output cut, of course.

Note: Genkernel initramfs output cut.

• Lets get the source

git clone https://github.com/jeekkd/gentoo-kernel-build.git && cd gentoo-kernel-build

• First we must change the scripts permissions. This will make the script readable, writable, and executable to root and your user

sudo chmod 770 build-kernel.sh

Note: This script can detect .configs in your current directory if you want to use your own custom configuration instead of your running kernels configuration as an example

• Now you launch the script like so

sudo sh build-kernel.sh
