The Unity Linux build3 internal ISO came out today. There's more to be done to create an actual LiveCD. There's still some arguing as to which window manager would be included in a later release. Something physically small, with few dependencies and with reasonable functionality. To me, that leaves about a half a dozen to choose between.
I've downloaded build3 and I'll check it out when I have some time. There's a tutorial which has to be rewritten to help our packagers out.
Since the toolchain also got updated, two RPMs I packaged have to be redone.
