Bug#746596: grub-install --disk-module option is referenced in the help, but no longer works

[Andras Korn]

Package: grub2-common
Version: 2.02~beta2-9
Severity: normal

Hi,

grub-install: --disk-module: (PROGRAM ERROR) Option should have been recognized!?

However, the help clearly states it's supported, and it used to work with
earlier versions:

grub-install --help                                                                                                                          :(
Usage: grub-install [OPTION...] [OPTION] [INSTALL_DEVICE]
Install GRUB on your drive.
[...]
      --disk-module=MODULE   disk module to use (biosdisk or native). This
                             option is only available on BIOS target.
[...]

I have a box that only boots if I use grub-install --disk-module=ahci. I
dare not reboot it with the new grub version because if it doesn't boot, it
takes quite long to fix.
