Okay, I can switch to xorriso, too. But I would assume I would have
to tune more options then.
Currently, we have:
# Common mkisofs options when creating CDs
add_mkisofs_opt $CDDIR/../$N.mkisofs_opts "-J -joliet-long"
add_mkisofs_opt $CDDIR/../$N.mkisofs_opts "-cache-inodes"
add_mkisofs_opt $CDDIR/../$N.mkisofs_opts "-l"
(...)
add_mkisofs_opt $CDDIR/../$N.mkisofs_opts "-G
$CDDIR/../CD1/boot/grub/sparc64-ieee1275/cdboot.img -B ..."
Would it be enough to just switch to xorriso here?
