You are ejecting the root disk? Well, that's difficult to get right.
You could transition back into an initrd of some kind and print the
Or you could print this message from a script in
/usr/lib/systemd/system-shutdown and hope for the best. (And turn off
console printk output via /proc/sys/kernel/printk first). Since the
systemd-shutdown binary (which runs at the very end) locks itself into
memory you might be able to get away with that. That said, the initrd
thing is the only fix that would really get this right.
