Re: Bug#927892: grub-ieee1275-bin: Please add bootinfo.txt for sparc and sparc64

Hi,

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

  $ xorriso -indev debian-10.0-sparc64-grub-NETINST-1.iso \
            -report_system_area plain
  ...
  Volume id    : 'Debian 10.0 sparc64 n'

  SPARC GRUB2 core   : 1748992  453104
  SPARC GRUB2 path   : /boot/core.img

xorriso reports /boot/core.img as "SPARC GRUB2 path", because it was
recognized as comming from the same disk inode as /boot/grub/core.img
and thus shares the content blocks with it:

  $ xorriso -indev debian-10.0-sparc64-grub-NETINST-1.iso \
            -find /boot/core.img -exec report_lba -- \
            -find /boot/grub/core.img -exec report_lba --
  ...
  Report layout: xt , Startlba ,   Blocks , Filesize , ISO image path
  File data lba:  0 ,      854 ,      222 ,   453104 , '/boot/core.img'
  Report layout: xt , Startlba ,   Blocks , Filesize , ISO image path
  File data lba:  0 ,      854 ,      222 ,   453104 , '/boot/grub/core.img'

So all is well. Except the nearly zero content of bytes 512 to 767 of
the ISO.


Have a nice day :)
