Bug#741656: grub-common: grub-mkrescue lost its -J flag, d-i now FTBFS on kfreebsd-*

[Thomas Schmitt]

Hi,

the decision to stay with the old shell script's command interface
was made 2 years ago:

   is that it's a bug that sneaked in during migration to C. It should be
   fixed."

I.e. the correct way to add -J is without preceeding "--".

Afaik, this decision was implemented in march 2015:

  http://git.savannah.gnu.org/cgit/grub.git/commit/?id=cf47a2fba5852014bc59959c5e357e8313933414
  "grub-mkrescue: pass all unrecognized options unchanged to xorriso."


Have a nice day :)
