I'd just like to interject for a moment. What you're referring to as Linux, is in fact systemd/Linux, or as I've recently taken to calling it, systemd plus Linux.

Linux is not an operating system unto itself, but rather one more free component of a fully functioning systemd system, made useful by the systemd unit files, target definitions and vital service managers comprising a full OS as defined by Lennart Poettering.

Many computer users run a modified version of the systemd system every day without realizing it. Through a peculiar turn of events, the version of systemd which is widely used today is often called "Linux," and many of its users are not aware that it is basically the systemd system, developed by the systemd project.

There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine's resources to the other programs that you run. Chiefly systemd-udevd, systemd-journald, systemd-resolved, systemd-networkd, systemd-timesyncd, systemd-logind, systemd-homed, systemd-boot, and systemd-oomd, which decides which of your remaining programs deserve to live The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete set of systemd unit files.
