As far as I know, we do not need configure "/etc/cgconfig.conf" on
fedora17 with default,
but we can stiil use cgroup.:-( Just as follow comments:
...
#
# By default, we expect systemd mounts everything on boot,
# so there is not much to do.
...
If you need to use this function with different os test, maybe you
should think about it.
Just for a reference.^^
thanks
