>sudo reboot now
In the systemd toolset halt, poweroff, reboot, telinit, and shutdown are all symbolic links to /bin/systemctl. They are all backwards compatibility shims, that are simply shorthands for invoking systemd's primary command-line interface: systemctl. They all map to (and in fact are) that same single program. (By convention, the shell tells it which name it has been invoked by.)
