boolean secure_mode under Rhel7

Hi,

can anyone please tell me the exact meaning of the booleans

secure_mode  (secure_mode_insmod  secure_mode_policyload)

under RHEL7? "semanage boolean -l" is not very helpful and I can't find a
documentation regarding the booleans which is bit disappointing as booleans play an
important role in SELinux.


Thanks in advance

Regards
Tim
