My image was only a proof of concept that ED could be dist-upgraded to Squeeze. It has some flaws (e.g. /etc/groups is missing accidentally) and the software installed is only what I needed in the image.

I never intended it to be used by end-users, but if you're fine with the limitations you can use it as well. But since Estel's image is based on mine there's nothing that my image can do that Estel's can't.
