Oh, I see: this flag is passed through grub-mkrescue to mkisofs. I
guess this is an alias for the -J flag to mkisofs? Strange that I
don't see it documented in either mkisofs(8) or grub-mkrescue(1). It
looks like we're passing -J to mkisofs/xorriso on alpha and hppa, so
my feeling is that we should just use it on all platforms. I'm happy
to adjust the patch when I commit it.
