We shall open the Tanenbaum, now in its fifth edition circa 2023, no doubt still taught to students all over the world:

> Processes are created in Linux in an especially simple manner. The fork system call creates an exact copy of the original process.

> The Linux sequence of clone plus exec is yet more orthogonal, since even more fine-grained building blocks are available. As a general rule, having a small number of orthogonal elements that can be combined in many ways leads to a small, simple, and elegant system.

Yup, still the same bullshit. It is not elegant, it is not fine-grained, it is not simple, it is certainly not small.
