That's exactly the layout `build.zig` assembles. It builds `src/efi.zig` for the
`uefi` target, installs it to `esp/EFI/BOOT/BOOTX64.efi`, and drops the kernel ELF
at `esp/danos`. The `run-efi` step then points QEMU at OVMF (UEFI firmware for
at `esp/danos`. The `run-x86-64` step then points QEMU at OVMF (UEFI firmware for
virtual machines) and presents that `esp/` directory to the guest as a FAT drive.
The firmware finds `BOOTX64.efi` and runs it — that's our `main()`.
