FYI: By default, Ctrl-Alt-Del reboots the machine. As has been pointed out once in this list (thanks to Michael Biebl), you can have Ctrl-Alt-Del power off the machine by adding a link /etc/systemd/system/ctrl-alt-del.target pointing to /lib/systemd/system/poweroff.target. # ln -s /lib/systemd/system/poweroff.target /etc/systemd/system/ctrl-alt-del.target However: if you then keep Ctrl-Alt-Del pressed for a second, the machine still reboots. That way, you could use Ctrl-Alt-Del for both poweroff and reboot.
