Ask HN: Why do people refer to Linux as an OS when it is just a kernel?

Why do people call businessmen "suits"? Or say that "planes fly" but not that "submarines swim"? When and where does an aircraft carrier "set sail"?

What exactly is "pre-boarding" at an airport?

Because "Operating systems based around the Linux Kernel, excluding Android" doesn't roll of the tongue so nicely.

Everyone knows that when someone says "Linux" he means a certain category of Operating Systems.

Because Linux is an operating system. Linux can run user-space programs without any user-land.

Because the distinction is meaningless for most people.

This is basically the argument, yeah.

Theoretically one could also describe the BSD kernel in this way, even though the projects are more "batteries included" in a sense. But nobody does that, because we just assume that if you're talking about BSD, you're not talking about ripping the userland out wholesale and replacing it. Why not? It's just common convention.
