Should the two systems share /boot/efi?
Ideally yes, although it's not required by the UEFI spec.
As I understand it, the answer is yes: /boot/efi is universal on a
machine. It is where the firmware goes to load things. Not just OS
bootloader: manufacturer-supplied EFI utilities can live there too.
But Fedora, by default, wants to create a new /boot/efi.
What is the right thing to do? What will work?
Either but it's simpler for future troubleshooting if you have one ESP per drive.
It's only particularly important to have one when dual booting Windows because it gets
pissy if there are two ESPs.
In the current installation, I've forced Fedora to use the existing
/boot/efi. I guess I'll see how that turns out.
That's fine.
