cpegel / chroot-guide

Created September 17, 2015 17:31

This is a guide on how to create a chroot in archlinux and downgrade it to a specific date. This is useful when trying to compile old kernels that don't build with new gcc versions.

	#
	# Setting up an archlinux chroot environment
	#

	# install devtools for bootstrapping
	sudo pacman -S devtools
	# create chroot environment with base-devel packages
	mkarchroot mychroot base-devel
	# enter the chroot
	sudo arch-chroot mychroot /bin/bash
