Linux

Linux is a UNIX-like kernel that was created in 1991 by Linus Torvalds. Originally written for the i386 family of computers, it has been ported to many other architectures as well. It is available as free software and forms an essential part of the GNU/Linux operating system, which is often referred to as "Linux" by mistake. Many distributions of GNU/Linux are available which allow users to easily install a GNU/Linux system from pre-built binaries, rather than compile it all themselves.

At the time of writing, there are no known ways to install a GNU/Linux distribution onto the PS4. The proprietary system software does not offer any method of allowing the user to install third party operating systems and it is likely that the PS4 is encumbered with digital restrictions management in order to prevent the user from doing so.
