That makes no sense as this parameter just provides the path to the HFS filesystem. If you don't provide this paramemter, how is grub-install supposed to know where to install the files? However, the problem is that GRUB has only a bless command but no command to set the tbxi attribute on the BootX bootloader file as explained here [1].
