Linuxbased

Linuxbased or Linux-based describes software, devices, or operating systems built around the Linux kernel. In practice it usually means a system that combines the Linux kernel with a user space built around GNU or compatible components, although other userlands exist. The term contrasts with operating systems built on other kernels.

Since the release of the Linux kernel in 1991 by Linus Torvalds, Linux-based systems have grown to dominate servers, desktops, and many embedded devices. The term covers a wide range from full-fledged desktop distributions to lightweight embedded firmware. Android, while mobile-focused, is Linux-based but uses a different user-space and app framework.

Key components include the Linux kernel itself; a user-space environment, often GNU or POSIX-compliant; a C library such as glibc; an init system; device drivers; and a package manager. Many distributions differ in package managers (apt, dnf, pacman, etc.), system initialization, and default software.

Notable Linux-based operating systems include Debian, Ubuntu, Fedora, OpenSUSE, and Arch Linux. In embedded and specialized environments, OpenWrt, Yocto-based systems, and Raspberry Pi OS are common. Linux-based devices range from personal computers to servers, routers, TVs, and automotive systems.

Licensing and development: the Linux kernel is released under the GPL, and most userspace components are open source. Development is collaborative and distributed, with thousands of contributors and a wide ecosystem of distributions, vendors, and communities.

Common clarifications: Linux refers to the kernel; Linux-based describes OSes using that kernel. Some argue for the term GNU/Linux to recognize the traditional GNU userland, though usage varies. The landscape emphasizes openness, interoperability, and modularity.
