Wait what? What happens if the process manager crashes if you're running non-systemd: you might respawn it but not be able to log the fact that you did so. Worst case, you fail to respawn it and your system crashes.

What happens if the process manager crashes if you're running systemd: the process manager is in PID1 (or, equivalently, in a tightly coupled process that PID1 depends on - because the whole point of your post was that you can never get to a state where PID1 is working but logging isn't working), so your system crashes, every time. How is that better? And if that's really what you want, it's easy to configure a decoupled init system to do that.

Hey, some people like their logs to be sent as email. Maybe we should move sendmail into PID1 as well.
