The BSDeviant project produces a free, FreeBSD-based UNIX-like operating system. Our whole distrobution is currently under 210MB and FULLY operates from a mini-cdr (or regular cdr) without the need to install anything on your hard drive. Our efforts are on 'ease of use' (for both new users and power users), security, and keeping our code as portable and stripped down as possible. "Unix; anytime, anywhere."
