I'm confused what image(s) you're referring to because, e.g.
Fedora-Cloud-Base-Rawhide-20210621.n.0.aarch64.raw has this partition
scheme:
Number Start (sector) End (sector) Size Code Name
1 2048 1230847 600.0 MiB EF00 EFI System Partition
2 1230848 3327999 1024.0 MiB 8300
3 3328000 10483711 3.4 GiB 8300
Do you want the 1st partition to also have BIOS Boot? (partition type
guid 21686148-6449-6E6F-744E-65656445464) GRUB maintainers have said
1 MiB is sufficient in the past; so I just want to make sure the first
partition you're referring to should have both this particular type
GUID and be 4 MiB? I don't think GRUB has exclusivity over this guid,
and was always intended to be generic, I'm just not aware of any
bootloader that uses it.
Also, the scope of the hybrid UEFI/BIOS change is limited to x86_64,
while we could incidentally add BIOS Boot to the aarch64 images, I
don't expect we'd actually put anything there. It'd be outside the
scope of the change proposal.
