I first started using GNU/Linux (with sysvinit) in 2000. I still remember a) finding runlevels incredibly confusing, b) finding the entire concept stupid when I finally understood them, and c) the sense of relief I felt when I discovered FreeBSD in ~2003 and the fact that it pretty much did not have this nonsense. There used to be a single-user mode that was required for certain tasks, maybe that still is a thing - but even so, it was much easier to understand than System V init.

So let me rephrase my statement, I hope that if they replace the good _new_ rc, they keep the interface as simple. For all I care, it would not have to be exactly the same, but I sure hope it stays as simple. The fact that on FreeBSD, I just need to look at a single text file with an easy-to-read-and-edit format to see what is going on, is one of FreeBSD's greatest virtues, IMHO.
