Hi,
reviewing my grub-mkrescue 1.98 test script
i see these options which will cause the files
in /boot to have low block addresses:
xorriso ... -as mkisofs ... \
--sort-weight 0 / --sort-weight 1 /boot \
...
The boot catalog gets a low LBA by default.

Hi,
i have to correct myself:
The boot catalog of grub-mkrescue has no ISO-path
anyway (no option -c).
There is a boot catalog path in grub-mkrescue.

Have a nice day :)

If that fails, then ./configure aborts after
