+- boinc-client.service: replace ControlGroup= by Slice=, since
+  ControlGroup is gone since systemd-205 already. We now use the
+  "background.slice". Configuration of the background.slice is
+  left to the administrator since it may be shared by other
+  packages, and is subject to preferences. If you need some default
+  to begin with for the first time,  use
+  `systemctl set-property background.slice CPUShares=2`.
