You need to turn off unconfined_t user to make this work, especially
as root, and then use sysadm_t.


# semanage boolean -l | grep secure
secure_mode                    (off  ,  off)  disallow programs, such
as newrole, from transitioning to administrative user domains.
secure_mode_policyload         (off  ,  off)  prevent all confined
domains from loading policy, setting enforcing mode, and changing
boolean values.  Set this to true and you have to reboot to set it back
secure_mode_insmod             (off  ,  off)  disallow programs and
users from transitioning to insmod domain.
