There are BSDs as well. I wonder how FreeBSD or OpenBSD is going to comply, if at all. There may be a way out of it, too, I am not sure. Perhaps a no-op.

I also wonder how non-systemd Linux is going to handle it. I mean ultimately it may be baked into the kernel in some way or another. It would be pretty sad though.

In any case, I agree. This is just the first step.
