systemd-206 doesn't support ControlGroup anymore, journal shows: systemd[1]: [/usr/lib64/systemd/system/rtkit-daemon.service:27] Unknown lvalue 'ControlGroup' in section 'Service' This needs to be outsourced into a kind of slice unit: rtkit-daemon.slice
Cf. Debian bug report and fix that went into Debian rtkit_0.11-2: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=747568
