#
# arch-bootstrap: Bootstrap a base Arch Linux system.
#
# Dependencies: coreutils, wget, sed, gawk, tar, gzip, chroot, xz.
# Bug tracker: http://code.google.com/p/tokland/issues
# Contact: Arnau Sanchez <tokland@gmail.com>
#
# Install:
#
# $ sudo install -m 755 arch-bootstrap.sh /usr/local/bin/arch-bootstrap
#
# Some examples:
#
# $ sudo arch-bootstrap destination
# $ sudo arch-bootstrap -a x86_64 -r "ftp://ftp.archlinux.org" destination-x86_64
#
# And then you can chroot to the destination directory (default user: root/root):
#
# $ sudo chroot destination
#
set -e -o pipefail -u
# Output to standard error
stderr() { echo "$@" >&2; }
# Output debug message to standard error
debug() { stderr "--- $@"; }
# Extract href attribute from HTML link
extract_href() { sed -n '/<a / s/^.*<a [^>]*href="\([^\"]*\)".*$/\1/p'; }
# Simple wrapper around wget
fetch() { wget -c --passive-ftp --quiet "$@"; }
# Packages needed by pacman (see get-pacman-dependencies.sh)

修改DEFAULT_REPO_URL="http://mirrors.kernel.org/archlinux" DEFAULT_ARCH=i686
然后 sudo sh ./arch-bootstrap.sh -a x86_64 /mnt/ ...
修改 /mnt/etc/pacman.conf中 Architecture = x86_64 或者 Architecture = i686
然后
# mount -t proc none /mnt/proc

# mount -o bind /dev /mnt/dev
# mount -o bind /dev/pts /mnt/dev/pts
然后
# chroot /mnt bash
# pacman -S base base-devel grub
