Adding another EFI partition should work, but I don't see how they could
share one. There's a single Fedora directory in there, so each install
would overwrite the files of the other. The grub.cfg can only point to
one set of boot loader entries.
And that means sharing one ESP means sharing /boot - yeah. Hmm. I'll
have to test it but I'm pretty sure it's a fairly simple post-install
fix to get that to work. I'm not totally certain how blscfg.mod parses
/boot/loader/entries containing bls snippets with two machine IDs.
Ohhhh I just thought of something. F32 and older depend on grubenv to
store part of the kernel command line variables. So I think it will be
necessary to do an F32 F33 side by side install for it to work. Two
F32's side by side will compete over the single grubenv.
