As of grub2 >= 2.02-95 on redhat family distros, calling grub2-install on an EFI partition will fail with: "this utility cannot be used for EFI platforms because it does not support UEFI Secure Boot." This version of grub is now in centos8-stream and non-eus repos of RHEL-8. It is not currently possible to build whole-disk UEFI images on these distros, and when this package is promoted this will also affect centos8 and RHEL-8 eus. The grub maintainers made this change because the grub2-install generated /boot/efi/EFI/BOOT/BOOTX64.EFI will never be capable of booting with Secure Boot. This change defines a $EFI_BOOT_DIR for every distro element. When directory /boot/efi/$EFI_BOOT_DIR exists a grub.cfg file in will be generated there. This change also installs the shim package on redhat family distros, which installs a copy of the shim bootloader to /boot/efi/EFI/BOOT/BOOTX64.EFI. Using centos as an example, this allows UEFI to boot the shim /boot/efi/EFI/BOOT/BOOTX64.EFI which then chains to /boot/efi/EFI/centos/grubx64.efi. If /boot/efi/$EFI_BOOT_DIR doesn't exist (such as for Ubuntu, /boot/efi/EFI/ubuntu) the current behaviour of running grub-install to generate /boot/efi/EFI/BOOT/BOOTX64.EFI will continue. For distros such as Ubutnu where packaging does not populate /boot/efi/EFI/ubuntu with .efi files, secure boot can be added in the future by copying .efi files to /boot/efi/EFI/ubuntu and copying the shim file to /boot/efi/EFI/BOOT/BOOTX64.EFI.

Image building tools for OpenStack ================================== ``diskimage-builder`` is a flexible suite of components for building a wide-range of disk images, filesystem images and ramdisk images for use with OpenStack. This repository has the core functionality for building such images, both virtual and bare metal. Images are composed using `elements`; while fundamental elements are provided here, individual projects have the flexibility to customise the image build with their own elements. For example:: $ DIB_RELEASE=bionic disk-image-create -o ubuntu-bionic.qcow2 vm ubuntu will create a bootable Ubuntu Bionic based ``qcow2`` image. ``diskimage-builder`` is useful to anyone looking to produce customised images for deployment into clouds. These tools are the components of `TripleO <https://wiki.openstack.org/wiki/TripleO>`__ that are responsible for building disk images. They are also used extensively to build images for testing OpenStack itself, particularly with `nodepool <https://docs.openstack.org/infra/system-config/nodepool.html>`__. Platforms supported include Ubuntu, CentOS, RHEL and Fedora.
