Hi,

Looks good. Viewing xorriso arguments in /mnt/iso/.disk/mkisofs ...
looks good too.
The ISO is now added to my collection of bootable ISOs for regression
test. My test loop checks whether the ISOs which are repacked from
existing

Hi,
xorriso-wise, the debian-10.0-sparc64-grub-NETINST-1.iso looks ok:

Hi,
there is a copy of the -G image file in the ISO:
/boot/grub/sparc64-ieee1275/cdboot.img
It has only 512 bytes. Very non-zero.

libisofs overwrites it completely at ISO production time.
See

correctly and boots with GRUB on CD. We can finally get rid
of SILO \o/.
Thanks everyone for the help!

I think you forgot -o result.o and -V Volume_Id.
They are all in the list of emulated options (xorriso

It's 512 to 1023, of course.
