kernel-build.sh

Easy-to-use Bash script to build/install Linux kernel on Gentoo-based systems

Copyright (C) 2017 I. Krivenko

Usage

kernel-build.sh saveconfig
kernel-build.sh loadconfig [kernel_version]
kernel-build.sh configure
kernel-build.sh build
kernel-build.sh install
kernel-build.sh oldconfig
kernel-build.sh minorupdate

Configuration variables are contained in the header of the script.

Features

• Copy kernel configuration file between ${SRC_DIR}/linux (/usr/src/linux by default) and ${CONFIGS_DIR} (/etc/kernel by default). loadconfig called without arguments tries to guess the best configuration file to load.

• Call make menuconfig/make xconfig depending on $DISPLAY environment variable being set (configure command).

• Call make oldconfig (oldconfig command).

• Build kernel and modules (build command).

• Install kernel/modules, run emerge -av1 @module-rebuild and update EFI boot record (install command). EFI manipulation requires sys-boot/efibootmgr to be installed.

• Run a sequence of steps to upgrade from kernel version x.y.z1 to x.y.z2 (minorupdate command).
