Instead of extracting a downloaded Gentoo filesystem tree into a file containing a reiserfs filesystem, create an ext3 filesystem inside a sparse file, mount it and debootstrap an up-to-date Debian system. Use this image as base for all UML guest images. Also, drop support for the various consoles and use xterm unconditionally.
