sudo systemctl status devstack@n-cpu.service
+Operating on more than one unit at a time
+-----------------------------------------
+
+Systemd supports wildcarding for unit operations. To restart every
+service in devstack you can do that following::
+
+ sudo systemctl restart devstack@*
+
+Or to see the status of all Nova processes you can do::
+
+ sudo systemctl status devstack@n-*
+
+We'll eventually make the unit names a bit more meaningful so that
+it's easier to understand what you are restarting.
