Booting from removable media bypasses the bootloader (does it
bypass UEFI?). Therefore it is enough to have a live OS on removable
media, equipped with this keysniffing kernel. But, sure, as Dr. Nikolaus
Klepp writes, it suffices to plug the disk into another computer.
I wonder if this UEFI thingy is anything else than a pure annoyance.
