TeraByte Unlimited

I understand there is nothing like PHYlock or VSS in Linux, so it is necessary to boot into IFL to image a Linux system.

I followed this KB some time back, and have IFL as option on the GRUB menu.

Now, can anyone provide any guidance on how to update the IFL that is in that partition?

Is it as simple as mounting the IFL partition while running Linux, and extracting ifl_en_gui_x64-363.zip into it?
If not, what is the procedure?

Reviewing the install process, I see it is possible to install in a directory in the Linux system, or to install in a partition using the makeHDD script.
How can I tell which method I used? From the running IFL environment, could I tell if I had previously run makeHDD? Could I tell if IFL was in its own partition or running from the main ext4 partition of Ubuntu? Looking at the partitions doesn't give a clue - there is no partition called "IFL" or "Terabyte" or similar.

Presumably to update IFL I would follow these steps:
1) run sudo makeGRUB and Select "Uninstall Grub boot files for IFL" on the main menu, which would remove the IFL files from /boot/ifl
2) extract the latest IFL ZIP file to the IFL folder in Ubuntu,
3) run sudo ./setup
4) run sudo makeGRUB and sudo makeHDD

Correct?
