Why would you want the EFI system partition inside of a RAID volume that's not understood by your system firmware?

Why would you want the EFI system partition inside of a RAID volume that's not understood by your system firmware?
- bradfa 8y agoWhen my OS updates the bootloader it stores in the EFI system partition, I want that data to be RAIDed. I set the EFI boot order to use the first disk's EFI system partition then the second disk's. Because at the OS level they are RAIDed and because I put the mdadm metadata at the ends of the disks, the UEFI firmware sees them as normal GPT partitions (with the secondary GPT partition table corrupted at the end of the disk due to mdadm data). When the EFI firmware runs, it should only be performing reads from either of the disks and even if one entire disk is dead it can still boot the system.
