UEFI Support
============
Introduction
------------
Some devices have firmware bugs which mean they do not include a valid ESRT
table in old firmware versions.
Create a 'fake' UEFI device with the lowest possible version so that it can be
updated to a version of firmware which does have an ESRT table.
GUID Generation
---------------
All the HwId GUIDs are used for the fake UEFI device, and so should be used in
the firmware metadata for releases that should recover the system.
Vendor ID Security
------------------
The vendor ID is set from the BIOS vendor, for example `DMI:LENOVO`
