cgmanger 0.35-1 will auto-enable cgmanager under systemd. (Note that it does not change the setting if cgmanager is being updated rather tha ninstalled). This should fix this bug. If you continue to have problems, please let us know.

(0.35-1 was uploaded to debian a shor ttime ago, should sync to vivid soon)
