  "Make a grub-efi-netboot package named NAME, which will be able to boot over
network via TFTP by accessing its files in the SUBDIR of a TFTP root directory.
This package is also able to boot from local storage devices.

A bootloader-installer basically needs to copy the package content into the
bootloader-target directory, which will usually be the TFTP root, as
'grub-mknetdir' will be invoked already during the package creation.

Alternatively the bootloader-target directory can be a mounted EFI System
Partition (ESP), or a similar partition with a FAT file system, for booting
from local storage devices.

The name of the GRUB EFI binary will conform to the UEFI specification for
removable media.  Depending on the system it will be e.g. bootx64.efi or
bootaa64.efi below SUBDIR.

The SUBDIR argument needs to be set to \"efi/boot\" to create a package which
conforms to the UEFI specification for removable media.

The SUBDIR argument defaults to \"efi/Guix\", as it is also the case for
'grub-efi-bootloader'."
