    If the ISO image has a FAT partition and the image is written
    to a flash drive, then it is possible to write to this partition
    of the flash drive.
    This is necessary, for example, if the user
    does not want to install the system, but wants to constantly work
    in LiveCD mode with or without recording sessions.
    In order for this code to work, you need to make changes
    to the FAT partition of the image on the flash drive:
    Add the 1st line to the grub.cfg file:
    set pfxfat=${prefix}
    Write a 1kb file grubenv.
    If grub.cfg contains a line like '^default=id',
    then the read value is not used.
