overcloud-secure-uefi

CAUTION: This element is part of the security hardened images feature, that is delivered in this release as tech preview. The following element is not intended for production usage.

overcloud-secure-uefi is an element to add extra security hardening features to the tripleo images: partition creation and unsafe package uninstall. This element is the equivalent of overcloud-secure one, but is used when needed to build images that are capable of booting from uefi.

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.
