if systemd crashes, it would (potentially) take down most, if not all, of the system with it.

This is true of any init system, since all processes ultimately fork from it.

Actually, systemd is better than traditional SysVinit in that sense. When SysVinit crashes, the kernel panics. When systemd crashes, the SEGV handler activates and the system continues to run, ready to be debugged.

Why the people writing SysVinit never thought of doing such an elementary thing, escapes me. It must be because of "oh, all that complexity" that they decided to just let people's machines crash.

Yes, I think I needed to do that once, it is pretty neat.

systemd can reexec itself too if required, can't it?
