Is that one EFI per OS, or multiple identical EFI? :-)

Neither. Multiple possibly not identical EFI partitions

is completly off-topic BTW

how is that related to RAID at all?

Can you elaborate ?

Mirroring with one EFI partition per OS does not make much sense.
And it would not be universal if it required identical partitions.

and how do you expect the UEFI smell which one is supposed to be 
booted from?

Boot* and BootOrder EFI variables exist for a purpose.

yeah and every of your operating systems is dealing with them authistic

you can't fix the design-errors of UEFI

But you can (and should) deal with them

and you do by simply have ONE ESP per machine and mirror them by hand as 
long as kernl-install is too dumb for simple post-scripts

finally: i am done with that thread, it's only wasting everybodys time 
and likely you need to make ypur own expierience and learn the hard way 
that multi-boot always was shit and become even more shit with EFI
