That sounds retarded. Why would anyone wanna change to that?
We want to change to "that" because basic idea is a good one. The ability to start services in parallel, socket activation, and cgroups for process group management are all good things. The problem with systemd is not so much these ideas, but the implementation. To put it bluntly, the developers are all "superstar" jerks who wouldn't know usability if it hit them over the head.
They designed an ugly interface with way too much automatic magic that no doubt is perfectly obvious and correct to them, but abstruse and incomprehensible to anybody outside their little circle. Then they wrote a couple of "howto" articles on complex sysadmin tasks that almost nobody has to do, and declared documentation complete. To do a simple task, like writing a service file, or God forbid, changing the getty program you want to use, requires a monumental effort of sifting through disconnected, unintuitively named man pages.
systemd: good idea, horrible implementation.
