Archboot Allinone ISO Howto:
(Quick regeneration of installation media with latest available core packages)

Requirements:
- x86_64 architecture
- archboot ISO
- ~ 3GB free space on disk

Create archboot chroots:
  # install archboot
  pacman -S archboot
  # create x86_64 chroot
  mkdir <x86_64_chroot>
  pacman --root "<x86_64_chroot>" -Sg base --noconfirm --noprogressbar
  # create i686 chroot
  mkdir <i686_chroot>
  linux32 pacman --root "<i686_chroot>" -Sg base --noconfirm --noprogressbar

Enter archboot chroot like this:
  mount -o bind /dev <chrootpath>/dev
  mount -o bind /tmp <chrootpath>/tmp
  mount -o bind /sys <chrootpath>/sys
  mount -o bind /proc <chrootpath>/proc
  cp -a /etc/mtab <chrootpath>/etc/mtab
  cp /etc/resolv.conf  <chrootpath>/etc/resolv.conf
  # enter chroot
  chroot <chrootpath>

Install archboot and update to latest packages:
  # update in both chroots to latest available packages
  pacman -Syu
  #install in both chroots archboot:
  pacman -S archboot

Generate images:
  # run in both chroots (needs quite some time ...)
  archboot-allinone.sh -t
  # put the generated tarballs in one directory and run (needs quite some time ...)
  archboot-allinone.sh -g

Finished you get a burnable iso image, a rawwrite usb image 
and a hybrid image which is both in one.

Don't forget after chroot leaving:
  umount <chrootpath>/dev
  umount <chrootpath>/tmp
  umount <chrootpath>/sys
  umount <chrootpath>/proc

Have fun
