It really isn't. SystemXVI is relatively novel as far as init system designs go. It's a more modular and pluggable Solaris SMF-like design (no XML configuration, don't panic), designed for portability at that.
Point taken, it would be nice if someone could start a comparison table between the different init systems, perhaps on Wikipedia? https://en.m.wikipedia.org/wiki/Init
We've also reinvented a car to go with our reinvented wheel, but we've also made is so the car is useless unless you use our wheels, and by virtue of having no other function, the wheel is also pretty useless unless you use it with our car.
But don't fret. Our car will provide you with it's own desktop built into the dashboard. Our car can communicate other cars, but only those of the same model, and even if our car doesn't have support for something you need yet, don't worry, as we'll build it directly into your car soon!
