[RFT] Truecrypt rescue image support

Hello, all. Basing my code on the information about truecrypt rescue
image layout from Attila Lendvai's project I wrote its support in GRUB.
Now you can do
truecrypt <truecrypt ISO>
boot
instead of having to go through ruby converter.
Since I don't use truecrypt myself I couldn't test it.
Could someone test it?
It's available from
http://git.savannah.gnu.org/cgit/grub.git/log/?h=truecrypt
@Attila: Thanks for figuring out the protocol. Do you have any problems
with that information being used in that way?

you're welcome and thanks for taking care of it!

yes, please feel free to use whatever i've provided for grub for the
benefit of humanity! :)

i don't have physical access to the machine where i tested it, so i
hope someone else will pick up the task and test it!

i may also get to it eventually, but not any time soon.

Hello,

Thanks for creating this great feature!  I recently had a chance
to test this but I ran into a strange problem when using the TrueCrypt
rescue ISO.  I created a bootable USB thumb drive which contained
the rescue ISO and loaded it on boot using the grub truecrypt module
you created.  The rescue ISO boots just fine but when I enter the
password I only get a "invalid password" prompt.  I can verify that
the password I am using is correct by burning the exact same ISO
to a CDR disk and booting with it.  When booted from a CD, the
password is accepted.

It is quite possible I am just configuring something wrong.  Following
are a complete list of steps that I used to create the bootable
thumb drive, maybe you will see something I am missing.

My Software Versions: OS: Ubuntu 14.04 LTS grub: 2.02~beta2-9 parted:
2.3

Complete Steps (assuming /dev/sdb is USB thumb drive)
  sudo parted -s -- /dev/sdb mklabel msdos
  sudo parted -s -- /dev/sdb mkpart primary fat32 1 -1
  sudo parted -s -- /dev/sdb set 1 boot on
  sudo mkfs.vfat /dev/sdb1
  sudo mkdir /mnt/truecrypt
  sudo mount /dev/sdb1 /mnt/truecrypt/
  sudo grub-install /dev/sdb --root-directory=/mnt/truecrypt --modules=truecrypt
  sudo cp truecrypt-rescue-cd.iso /mnt/truecrypt/boot

Then I created /mnt/truecrypt/boot/grub.cfg
  menuentry "Truecrypt Rescue" {
    truecrypt /boot/truecrypt-rescue-cd.iso
  }

At this point I use the thumbdrive to boot the target system.  I
select "Truecrypt Rescue" from the grub menu and the rescue image
boots OK.  However, as I mentioned before, the password is not
accepted.

I am able to help test if you can think of any steps I should try.

Best regards,

Sam Nelson
