Q: What is ROCK Linux ROCK Linux is a distribution development kit. People can use it to build their own Linux distributions. There are two ways of customizing the build of a new distribution in ROCK Linux: 1. The Configuration. ROCK Linux has a powerfull configuration system which gives the user full control over a wide range of options used during the build. This includes stuff like selecting the CPU optimisation, compiler, c-library, various install prefixes, packages to build or not to build, etc. 2. The ROCK Linux build system is designed to be flexible, open and easy to extend. So if any option is missing it's easy to add it. So there are two groups of ROCK Linux users: Those who are using a ROCK Linux based distribution and those who are using the ROCK Linux build system for building distributions.
