The command systemctl start x2gobroker-daemon will start the daemon but not return to the prompt. This is caused by the way DaemonContext() handles the parameter detach_process: "If unspecified (None) during initialisation of the instance, this will be set to True by default, and False only if detaching the process is determined to be redundant; for example, in the case when the process was started by init, by initd, or by inetd." But systemd is not recognized, so detach_process defaults to False. It has to be explicitely set to True. I tested the behaviour on Fedora 20, and the daemons both detach after this change.
