The thing is, what we called a linux distro, is not the same anymore. Linus wanted to make some kind of cheap (by price) UNIX.
With systemd, 2 fundamental pricniples of UNIX are broken:
(i) Make each program do one thing well. To do a new job, build afresh rather than complicate old programs by adding new features.
(ii) Expect the output of every program to become the input to another, as yet unknown, program. Don't clutter output with extraneous information. Avoid stringently columnar or binary input formats. Don't insist on interactive input.
So, probably distros shipping systemd should not be called linux distros anymore. It was already a mistake to call "Linux" distos. With systemd, linux distros are as close to unix as android does...
