What prevents us from having two EFI partitions?

The EFI standard?

I had understood that there can only be one EFI system partition. Maybe I am wrong; but we should investigate this.

"The globally unique identifier (GUID) for the EFI System partition in the GUID Partition Table (GPT) scheme is C12A7328-F81F-11D2-BA4B-00A0C93EC93B, while its ID in the MBR partition table scheme is 0xEF."

I.e. there is a paredefined GUID for that partition; if there are multiple ones, they'd get the same GUID which sounds like a recipe for desaster to me.

It doesn't even seem to be clear if another disk can have one, too:

But we should clearly get some authoritative answer from our resident EFI specialists (Raymund Will (?) - couldn't reach him on the phone just now).

Kind regards
