To be 🤓 really really nitpicky, and i’m writing this because I find it interesting, not an attack or whatever. A tongue in cheek AcHtUaLlY 🤓
GNU/Linux is the “whole operating system”, and everything else is extra. The usefulness of an operating system without applications is debatable but they 🤓 technically aren’t required to complete the definition of an operating system.
But this is also basically the debate of Linux vs GNU/Linux vs also needing applications to make a useful operating system.
Quoting wiki summary,
In its original meaning, and one still common in hardware engineering, the operating system is a basic set of functions to control the hardware and manage things like task scheduling and system calls. In modern terminology used by software developers, the collection of these functions is usually referred to as a kernel, while an ‘operating system’ is expected to have a more extensive set of programmes. The GNU project maintains two kernels itself, allowing the creation of pure GNU operating systems, but the GNU toolchain is also used with non-GNU kernels. Due to the two different definitions of the term ‘operating system’, there is an ongoing debate concerning the naming of distributions of GNU packages with a non-GNU kernel.
