It would also offer interesting migration benefits for Linux users wanting to try FreeBSD, allowing them to trivially create new FreeBSD installs under their existing Linux install. We had an SoC project last year but I'm not sure what the outcome was; it would be useful to give Fabio a ping and see how things are going. Obviously, anyone doing this project would need to manage the license issues involved carefully. Robert N M Watson Computer Laboratory University of Cambridge
