[arch-releng] new testbuild with preliminary nilfs2 support

Another archiso testbuild http://build.archlinux.org/isos/2010.12.06/ Changes: - aif, libui-sh from git. aif contains some filesystem refactorings and nilfs2 support - inclusion of nilfs-utils - archiso2dual split profile instead of basic because dual core image was 759MiB, now 686MiB - remove joe from package lists, joe is not in repos anymore (not yet committed in archiso git) * known issues: - interactive filesystem configuration interface is broken. (autoprepare does work). sorry about this, will fix.. - nilfs-utils is not in core so doesn't get installed to target yet Dieter
