NO LONGER MAINTAINED: Rootbox has largely been replaced by another, much better project I created: IsolateKit. Documentation is definitely still lacking, but it's overall a large improvement over Rootbox.
Rootbox is a tool that lets you create and distribute “boxes”: isolated environments designed for building code thanks to the power of chroots and mounts.
Unlike full-blown containerization tools like Docker and rkt, Rootbox is intentionally non-secure. This allows it to be incredibly lightweight, ideally suited for creating portable, reproducible development environments.
