Now that Linux 2.6.38 hits [core] we can enable xz compression in SquashFS images by default. I can not test it now, but is supposed to work fine. Go ahead and apply to master? https://github.com/djgera/archiso/compare/ce31b12654...4ea8b93f9c

Pushed all patches to master ([archlinux], [syslinux-iso] and [archiso2dual]). I guess next iso images will use XZ :). Good luck! -- Gerardo Exequiel Pozzi \cos^2\alpha + \sin^2\alpha = 1
