Recent changes to Metro have changed how container templates are organized.

On the surface, it's rather elegant. Stage4 and container artifacts are placed inside the build directory along the stage1/2/3, and there is a symlink outside the directory to the most current artifact. Just like how we handle stage3's.

But in practical use, I don't think this is ideal all by itself. The reason is that stage4's/containers/etc are not built all the time, and may not be built for every subarch for which there is a stage3. This makes it hard for users to find the best one for their particular system.

My suggested fix is to have an additional symlink structure, similar to the old:

funtoo-current/openvz/funtoo-openvz-corei7-latest.tar.xz -> /path/to/funtoo-openvz-corei7-2012-05-20.tar.xz

This would allow people to easily find the best optimized openvz template for their system.

I don't mind keeping the current design and just adding this on as an additional way (via symlinks) to get to container images. I think that would be the best of both worlds.
