Er, I meant /bin/systemctl reboot.

That's not how it's supposed to be.
Somehow these shell scripts replaced actual halt, reboot and poweroff.

My suggestion:

ln -sf /bin/systemctl /sbin/reboot
ln -sf /bin/systemctl /sbin/halt
ln -sf /bin/systemctl /sbin/poweroff

Or, even better:

apt install --reinstall systemd-sysv
