This means systemd has crashed for some reason. At this point it freezes
execution and doesn't allow any further actions.

Well, that's actually what's already happening. In postinst we run
systemctl daemon-reexec which will start the new binary and transfer the
state from the old process.

For some reason systemd crashed on your system before that happened.

Can you reproduce the crash or do you at least have a core file from the
crash? Do you have a complete journal log?
Which version of systemd was running (not installed) when you attempted
the upgrade?
