Automate most of the manual tasks described in the Arch Build System to build a custom kernel.

make

Once build is finished, you can install the kernel packages with the following commands:

cd build/package
pacman -U *.tar.zst

Before running this script, you need to install and configure modprobed , then run

make modprobed

Add configuration in file patches/config, then just run

make

Note that you can also use custom config with modprobed task

As described in makepkg doc, you can build the kernel faster by setting the following options in /etc/makepkg.conf :

MAKEFLAGS="-j$(nproc)"
BUILDDIR=/tmp/makepkg
