Mostly notes for myself:
I've realize that moving the initial binary location might also move the
VarStore (depending on how OVMF build is configured). The VarStore
location is used later by OVMF, if that location looks like a VarStore
(there is a header) then OVMF use it, otherwise OVMF simply initialise
it.

Anyway, just a reminder that I need to pay attention to where it is, as
maybe someone is trying to use it on HVM.
