The light iso is available to testing, do not expect too much. Basically I have removed the heavy applications for lighter versions. You still have a file-manager (mc) and media player (cmus) terminal based. Netsurf is much lighter although not feature rich. Thing is Archlinux is network based so if you do need Firefox, Gparted or any other application it can simply be installed (given a working network connection). Do not worry normal service will resume and I can now focus spring release.
