# Chroot to the system. But since the location of binutils are not in the same directories (Arch's default PATH only has "/usr/local/sbin", "/usr/local/bin", and "/usr/bin", whereas debian uses these directories as well as "/bin", "/sbin" and "/usr/sbin"), you should source the profile after chrooting otherwise, even simplest tools like `ls` won't be available directly other than specifying their whole path.
mount -t proc none /mnt/install/proc
mount -o bind /dev /mnt/install/dev
chroot /mnt/install /bin/bash
source /etc/profile
