bug#26815: [PATCH 0/3] Hybrid UEFI disk image

[Marius Bakke]

This ended up a lot simpler than anticipated.

These patches are on top of <https://bugs.gnu.org/26339>, but can be
ported to master since it ultimately didn't use any of the new tricks.

Test with:
  $ cp $(./pre-inst-env guix system disk-image --image-size=1G \
    gnu/system/install.scm) install.img
  $ chmod 644 install.img
  $ qemu-system-x86_64 -enable-kvm -m 512M -serial stdio \
    -bios $(guix build ovmf)/share/firmware/ovmf_x64.bin \
    -drive file=install.img,if=virtio

One caveat is that it probably only works on most(?) 64-bit systems.
Please test it on real hardware, especially older EFI systems. Not sure
what to do about 32-bit yet.

Marius Bakke (3):
  vm: Add support for arbitrary partition flags.
  vm: Support creating FAT partitions.
  vm: Support EFI boot in base image.
