ROCK Linux

ROCK Linux is a flexible Linux distribution Build Kit, i.e. it is a toolchain/framework for making your own Linux distributions.
Configurable build
You can configure your personal build of ROCK and easily build your own distribution. It is software for managing operating environments. In a way it is a software development toolkit for building OS solutions.

The available config options include, but are not limited to:

; Package Selection
: You can select the packages you want to have in your distribution. So packages you don't want or need are not built at all. A list of available packages can be found here.

; Compiler and Optimization
: You can select a compiler and optimization options for building your distribution. That enables you to highly optimize for your hardware. You can also build your entire distribution with the GCC Stack-Smashing Protector enabled for enhanced security.

; Dietlibc and uClibc
: You can use dietlibc or uClibc instead of the GNU LibC as your C library. That can be very useful e.g. for embedded systems.

; And much more ...
: Other options are: selection of an init-style and package manager, custom GNU configure options, cross-building, and much more. A major focus in the ROCK development always has been to make adding new features and config options as easy as possible.
Supported architectures
Most of the ROCK Linux development is done on x86 hardware. But ROCK Linux also supports the Alpha AXP, ARM, HPPA/HPPA64, IA-64, MIPS, PowerPC, SPARC 32/64 and x86-64 architectures. Others will follow and are easy to add.

The ROCK Linux Core has been ported to the PowerPC. This was done live, on stage at the Chaos Communication Congress 1999 in only 3 congress days. That was a very impressive demonstration of the high portability of ROCK Linux.
Targets
A "ROCK Linux Build Target" is a set of rules for creating a ROCK Linux based Linux distribution. The ROCK Linux build system has very flexible hooks which allow targets to modify the way the build system works. So targets can be used to create special-purpose distributions like single-disk routers, embedded systems, NCs (thin clients), set-top-boxes or cluster-nodes.
Building on a cluster
Building ROCK Linux can take a long time (a few days, even with state of the art hardware, if you build all packages with high optimization). To speed up build time it's possible to build ROCK Linux on a cluster of workstations.
