Support for security hardened images was delivered in Queens, not as TechPreview. Removing the section of README that indicates it is TechPreview. Change-Id: I579b1fdedcd23f8d004bb9ca6c8fedd29c33ac7c
overcloud-secure
overcloud-secure is an element to add extra security hardening features to the tripleo images: partition creation and unsafe package uninstall.
It includes the block-device-default definition, that creates independent partitions on the overcloud image, allowing those to accomplish the ANSSI security requirements. Please note that the sizes of the partitions may not be enough for production usage, they will need to be resized properly after deployment depending on the available disk size.
