RHCOS is UEFI capable but is missing the firmware support for Secure UEFI. As a result, on certain bare metal hardware and cloud providers (Azure Gen2) RHCOS will not boot. Our current EFI layout is: [root@ibm-p8-kvm-03-guest-02 boot]# find efi -type f -exec md5sum {} \; | sort 805369650ed821476003893402c7c8df efi/EFI/redhat/grub.cfg a1a08d1393070ef05a912cd08f132a70 efi/EFI/BOOT/grubx64.efi c748cde9827385f9832a4f0ab1f02550 efi/EFI/BOOT/BOOTX64.EFI We are missing: - shim64.efi: provides the MS signing key. - fbx64.efi: fallback shim in case a disk is moved - mmx64.efi: needed for key-enrollment for GPL compliance of the SHIM
Fix proposed for CoreOS Assembler. https://github.com/coreos/coreos-assembler/pull/1105
