Gentoo Linux: Operating system, Linux kernel, Portage (software), Package management system, Free and open source software, Software distribution, Ports collection, Gentoo Penguin

Gentoo Linux is a computer operating system built on top of the Linux kernel and based on the Portage package management system. It is distributed as free and open source software. Unlike a conventional software distribution, the user compiles the source code locally according to their chosen configuration. There are normally no precompiled binaries for software, continuing the tradition of the ports collection, although for convenience, some software packages are also available as precompiled binaries for various architectures. The development project and its products are named after the Gentoo penguin. Gentoo package management is designed to be modular, portable, easy to maintain, flexible, and optimized for the user's machine. Gentoo describes itself as a metadistribution, "because of its near-unlimited adaptability".
