Me ? I cannot even convince you or Vladimir :))

I understand that you propose a single interpretation mode
which shall be compatible with grub-mkrescue(.in) from
GRUB 2.00.
In the first thread about this topic, the wish was issued to
make the ISO producer behave like other GRUB tools.
Does any of them use ARGP_NO_ERRS ?

My proposal tries to keep old scripts runnable, while not
hampering the transition to the common interpretation style.
It also complains about now unsupported options of grub-mkrescue(.in),
wheras your poposal forwards them to xorriso. (If i get it right.)

At least it addresses my concerns about compatibility for
scripts.

If it gets implemented, then it should catch old options
  -v
  --version
  --modules
  --modules= 
  --override-directory
  --override-directory=

My proposal for -vi and --version was:
        {
          printf ("%s %s %s\n", argv[0], PACKAGE_NAME, PACKAGE_VERSION);
          exit (0);
        }
The others just issue an error message and exit, as i do not
know whether they would make sense in grub-mkrescue.c.


Have a nice day :)
