Linux distribution

Linux is a kernel whereas all the userspace? programs bundled with distributions, layout, and configuration techniques make up a distribution. Some are as minimalistic as Slackware, whereas Debian has one of the most extensive packaging and configuration programs included in the distribution. SuSE is the major European distribution. Based in Germany, it offers another extensive set of extras and its own installation/configuration tool in YaST?. One influential distribution is the USA-based Red Hat Linux and its various derivatives, such as Mandrake.

Almost all Linux users use a distribution, but it is actually possible to individually download, compile and install Linux and associated packages without making use of one. (See [Linux From Scratch Guide] for instructions.) The initial environment for this (kernel, compilation tools, ...) has to be present first -- either in the form of another compatible system, or provided by a "bare-bones" distribution.
