Thanks, Thomas. The xorriso report indicates that both BIOS and UEFI
boot images are present.
I notice that isohybrid is not present on my system. This might cause
silent failure of the isohybrid step. I suspect that this is another
missing dependency of live-wrapper. I have manually installed
syslinux-utils and will try again and report back.
