I am a bit concerned about having other subsystems muck with the systemd cgroup hierarchy, before systemd has set it up. I can see some elegance in having all code from the initrd that remains running during boot in a cgroup of its own, but that's probably orthogonal to finding a way to recognize processes not to kill at shutdown. Why? Because there's stuff like Plymouth which also stays around from the initramfs, but actually is something we *do* want to kill on shutdown.
