Bootstrap a base Arch Linux system from any GNU distro.
# install -m 755 arch-bootstrap.sh /usr/local/bin/arch-bootstrap
Create a base arch distribution in directory 'myarch' (i686 arch by default):
# arch-bootstrap myarch
The same but use arch x86_64 and a given repository source:
# arch-bootstrap -a x86_64 -r "ftp://ftp.archlinux.org" myarch
Once the process has finished, chroot to the destination directory (default user: root/root):
# chroot destination
Note that some packages require some system directories to be mounted. Some of the commands you can try:
# mount --bind /proc myarch/proc
# mount --bind /sys myarch/sys
# mount --bind /dev myarch/dev
# mount --bind /dev/pts myarch/dev/pts
