[arch-general] How to reboot remotely without hanging ssh session?

Guys, I remote administer one arch server and after moving to systemd I haven't found a way to reboot without hanging the ssh session. Prior to system, we could simply pass the shutdown command via ssh and the ssh session would complete/close before reboot took place: i.e. $ ssh remote.host.org "sudo shutdown -r now" However with systemd, using "systemctl reboot" the ssh session hangs until the remote host reboot or a timeout occurs. Is there a better way to reboot a remote server and avoid this? -- David C. Rankin, J.D.,P.E.
