Gentoo Linux
What Gentoo Linux is
Gentoo Linux is a free operating system based on Linux for desktop PCs, servers, embedded systems, small systems, and single-board computers. It can be adapted to different uses, with users choosing system settings through text files and tuning package or system-wide behavior with USE flags. Gentoo usually installs packages by compiling source code from upstream projects, while also allowing precompiled binary packages. Portage and emerge provide package installation and updates, and the ebuild repository supports both build approaches.
Gentoo does not require a particular system profile or desktop environment. OpenRC and systemd are supported init system options. Installation follows the stage3 method; Gentoo also provides minimal installation CDs and a LiveGUI USB image with KDE, built weekly for amd64. The system is available for many architectures, including x86, amd64, ARM, MIPS, PowerPC, SPARC, Alpha, IA64, HPPA, PPC64, ARM64, and 64-bit RISC-V. Stage downloads may include checksums and PGP signatures that users can verify. Gentoo maintains a security database with distribution advisories and a confidential route for reporting vulnerabilities. The operating system is free, with a listed price of $0.
