Re: I wonder why?
I seriously doubt the folks who will take over after Linus gets hit by a bus will be in any hurry to include anything anything to do with the systemd cancer in the kernel. Nothing that it does belongs in there. There are many reasons why init is separate from the kernel, and nothing they can add to the systemd cancer will ever change that.
With that said, I strongly suggest that anybody already using Linux and GNU FOSS solutions also look into the BSDs. All it will cost you is a little time ... and options are always good.
