The purpose of the group is to ensure not all tasks start in root,
root cgroup has all the resources. Once a task moves out of its
default group which is root by default, it cannot come back. That is
not a good situation. The default group solves these problems.
There is a simple way to disable this
Create /etc/sysconfig/cgconfig and add the following
CREATE_DEFAULT=no
