Package: vboot-kernel-utils
Version: 0~R106-15054.B-1
Severity: normal
File: /usr/bin/futility

Dear Maintainer,

# vbutil_kernel --pack /dev/mmcblk1p9 --keyblock 
/usr/share/vboot/devkeys/kernel.keyblock --signprivate 
/usr/share/vboot/devkeys/kernel_data_key.vbprivk --version 1 --vmlinuz 
/media/new+pstored+sysrq.dtb --bootloader /dev/null --config cmdline3 --arch 
arm64
FATAL: do_vbutil_kernel: Error reading bootloader file.

The same happens when you
  # > b
  # ... --bootloader b ...
and you need to printf '\0' > b for vbutil_kernel to accept it.

This appears to be a fake restrixion ‒
AFAICT the boot bundles on my chromebook are all-zero anyway,
and booting with the single-NUL-byte bootloader works.

So the --bootloader option should be optional,
or it should correctly accept empty files.

Best,
наб
