Mnix is a free, simple, and fast i686 GNU/Linux distribution, aimed at experienced users. It is a hybrid distribution; both precompiled packages and sources are supplied. The main focus is keep it simple and to be as Unix-like as possible, using "Free Software" only. Mnix is installed as a basic system with console-only tools, which forms the base which lets the user build a customized distribution (and even remaster it). Its main features are: Free Software only, BSD-style init scripts, only one shell (bash), a simple package manager (mtpkg), a ports-like repository structure called "mars" (the Mtpkg Applications Repository System), a simple filesystem hierarchy which adheres to the Unix philosophy, kernel-libre-only sources, a set of libraries and compilers for the most-used programming languages, and a complete set of shell packages (installable from the ISO) to set up in 30 minutes (more or less) a fully working console-based system. Mnix GNU/Linux is suitable for the somewhat-experienced user who prefers console admin tools to tweak the system, who prefers to compile packages with custom settings, and who wants to customize the kernel for his own system.
