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

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

Create archboot chroots:
  # install archboot
  pacman -S archboot
  # mount recent archboot image file as loop device
  mount -o loop <imagefile> <imagepath>
  # create x86_64 chroot
  mkdir <x86_64_chroot>
  /usr/share/archboot/installer/quickinst media <x86_64_chroot> <imagepath>/core-x86_64/pkg
  # create i686 chroot
  mkdir <i686_chroot>
  /usr/share/archboot/installer/quickinst media <i686_chroot> <imagepath>/core-i686/pkg
  # unmount iso file
  umount <imagepath>

Enter each 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:
  # configure pacman.conf and mirrorlist to your needs
  edit /etc/pacman.conf and /etc/pacman.d/mirrorlist
  # 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, to unmount binds for each:
  umount <chrootpath>/dev
  umount <chrootpath>/tmp
  umount <chrootpath>/sys
  umount <chrootpath>/proc

Have fun
