Rock Linux
ROCK Linux is a distribution build kit, a group of tools to build GNU/Linux distributions from source. It comes with a set of predefined distributions like the Crystal ROCK desktop target or the small, bootable bootdisk target, and allows users to easily customize the build process and create new targets.
The distributions that ROCK Linux generates are sometimes called ROCK Linux themselves, although the term ROCK Linux based distribution is more appropriate.
In a way ROCK Linux is a tool for managing OS solutions. It comes with the package managers mine and bize, the rocket tool for updates over network, and the ability to build (emerge) single packages into an existing Linux OS. For system administrators, a setup tool (stone) and reasonable System V style init scripts as well as other configuration files are provided.
The latest version of ROCK Linux is always available from the Subversion repository. They stopped createing official releases some years ago. Instead it is recommended that you take a svn trunk revision that works for you and branch of your distribution from that, maybe merging upstream changes from the repository to your version of ROCK Linux on demand or on a regular basis. The source filesystem layout of ROCK Linux is designed in a way that makes it easy for you to seperate your changes and enhancement from the core build system and the generic package build descriptions.
