This becomes quite confusing by the fact that even before the first "--" the non-dashed arguments are interpreted as options of xorriso's mkisofs emulation. (I understand this from the interaction via ARGP_KEY_ARG between util/grub-mkrescue.c and grub-core/gnulib/argp-parse.c) I would prefer to see a short mentioning that "--" has a special meaning for the mkisofs emulation too, and that the first "--" will not reach xorriso. But again: Is this substantial change of user interface intentional ? It makes the first "--" mandatory if any of xorriso's dashed arguments shall be used. This demand is new and surprising. Have a nice day :) Thomas
