Family of Unix-like operating systems This article is about the family of operating systems. For the kernel, see Linux kernel. For other uses, see Linux (disambiguation).

A Linux distribution is usually built around a package management system, which puts together the Linux kernel, free and open-source software, and occasionally some proprietary software. Many Linux distributions provide an installation system akin to that provided with other modern operating systems.
The portability section of the Linux kernel article contains information and references to technical details. Note that further components like a windowing system, or programs like Blender, can be present or absent. Fundamentally any software has to be ported, i.e. specifically adapted, to any kind of hardware it is supposed to be executed on.
Besides the Linux distributions designed for general-purpose use on desktops and servers, distributions may be specialized for different purposes including computer architecture support, embedded systems, stability, security, localization to a specific region or language, targeting of specific user groups, support for real-time applications, or commitment to a given desktop environment.
Linux is the leading operating system on servers (over 96.4% of the top 1 million web servers' operating systems are Linux), [82] leads other large systems such as mainframe computers, and is the only OS used on TOP500 supercomputers (since November 2017, having gradually eliminated all competitors).

systemd is a software suite that provides an array of system components for Linux [7] operating systems. The main aim is to unify service configuration and behavior across Linux distributions. [8] Its primary component is a "system and service manager" — an init system used to bootstrap user space and manage user processes.
However, they are accompanied by library operating systems (see also unikernel), providing application developers with the functionalities of a conventional operating system. This comes down to every user writing their own rest-of-the kernel from near scratch, which is a very-risky, complex and quite a daunting assignment - particularly in a ...
A Unix architecture is a computer operating system system architecture that embodies the Unix philosophy. It may adhere to standards such as the Single UNIX Specification (SUS) or similar POSIX IEEE standard. No single published standard describes all Unix architecture computer operating systems — this is in part a legacy of the Unix wars.
