stig.rules example in audit-2.3.7

Hello, I was looking through the stig.rules file that is provided with RHEL 6.6 and I noticed some differences that I couldn't find in the actual STIG. After looking at some of the items, I thought maybe they only apply to RHEL 7. Could someone provide some clarification on the following: - removed ftruncate - added open_by_handle_at - added finit_module - added sections regarding containers Thanks, Andrew Ruch
