For images which will never get to a CD it is safe to use -padding 0 .

\fB\-boot_image\fR "any"|"isolinux" "discard"|"keep"|"patch"
Defines the handling of an eventual boot image (El-Torito) which has been read
from an existing ISO image. All types ("any") can be discarded or kept
unaltered. The latter makes only sense if the format of the boot image is
relocatable without content changes.
.br
The boot image type "isolinux" can be kept unaltered (not advisable), or
discarded, or it can be patched to match its relocation. In the latter case
the resulting ISO image is bootable if the boot image was really complying
to the isolinux standard.
.br
Creation of new boot images is not yet possible.
.br
CAUTION:
This is an expert option. xorriso is not an expert yet.
It cannot recognize the inner form of boot images.
So the user has already to know about the particular needs of the
bootimage which is present on the input media.
Most safe is the default: "any" "discard".
