After 'having fun' with archboot, I finally got it working on both UEFI and BIOS. Just make sure that x86_64 and i686 archboot systemd container have proper package cache. This can be achieved by bind mounting host package cache '/var/cache/pacman/pkg' to chroot package cache. Also make sure that /tmp in which archboot-allinone.sh -g performed is large enough to hold image creation, at least 4GB. However, a very serious problem occured. The resulting Archboot dual iso doesn't properly contain all packages needed for installation. The most notable is 'libnftl'. 'systemd' (core) depends on iptables (core). 'iptables' can't be installed because 'libnftl' is missing (extra). This is serious problem that prevented archboot development for about two months. I know that 'archboot' only contains 'core' repository. As temporary solution, 'libnftl' should be added as 'SUPPORT_ADDITION' in archboot-svn.sh, so that users will be able to get a working installation by using only the 'archboot' image. I strongly suggest to move 'libnftl' to core repository to prevent this problem i.e. 'base' can't be installed without access to extra repository.
