dbus not starting [MAGEIA2]

Attempting to start the messagebus service fails (though the rc script indicates success onscreen) with this log entry:
systemd[1]: Failed to open private bus connection: Failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory
/var/run/dbus exists, but is empty.
I do have /var on a different filesystem from / (as I've always done).
