CrunchBang is a Debian GNU/Linux based distribution offering a great blend of speed, style and substance. Using the nimble Openbox window manager, it is highly customisable and provides a modern, full-featured GNU/Linux system without sacrificing performance.The primary aim of the CrunchBang project is to produce a stable distribution offering the best possible out-of-the-box Openbox experience. To achieve this goal, CrunchBang pulls many base packages directly from Debian's repositories, which are well-known for providing stable and secure software. Packages from CrunchBang's own repositories are then customised and pinned to the system to produce what is known as the CrunchBang distro.
Put simply; CrunchBang could be thought of as a layer built on top of Debian, specifically to provide a great Openbox experience.
CrunchBang uses the Openbox window manager. Openbox is lightweight and speedy, and as a result, CrunchBang is fast. Also, whilst CrunchBang is not primarily designed for older systems, it has been reported to operate very well where system resources are limited. Once installed, CrunchBang should boot-up and operate faster than a regular Debian GNOME/KDE installation.
