I think you hit it on the head to point out that the phrase is meaningless. The whole systemd phenomenon is very Freudian, right down to its name, it's as if systemd fans seek a single component to point at and call "the system", to worship as pater familias. "The system" will not only free you from being precise about what components serve what purpose, it will end all arguments and bring order to their lives in a way that decentralized purpose built components will not.

Maybe they should just use OS X and be done with it.
