Onebase is still a very new distribution - the first version appeared only in July 2003, and Onebase 2004 released in early January 2004 is a major rewrite and enhancement of the original concept. It started out as a source-based system, but with this release it embraced binary packages as well, becoming a hybrid. It is not based on any other major distro or package management system, instead it prides itself on doing things its own way. These are still the early days, but this is also what makes it an interesting distro, and the one to watch.
