We updated our Gentoo Linux base image today. The new image (still based on the current 2007.0) includes iptables and kernel sources by default as well as updated portage.
A few other minor changes (
USE="nptlonly" in make.conf) etc. are also corrected in this update.
As always, you can sync portage from our local portage tree and use our local distfiles mirror for Gentoo.
