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

Requirements:
- x86_64 architecture
- ~ 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 x86_64 container:
  systemd-nspawn --capability=CAP_MKNOD -M $1-$(uname -m) -D <x86_64_chroot>
Enter archboot i686 container:
  linux32 systemd-nspawn --capability=CAP_MKNOD -M $1-$(uname -m) -D <i686_chroot>

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 bunch of images.

Have fun
