GFI outlets do not work without a proper ground. (The "test" button
trips them, but the plug in tester will not). I know this because I
failed a CO because a GFI was on an ungrounded circuit (knob and tube).
I would up having to ground the whole circuit (which was wired with
14/2...just that the ground was "floating").

suggests using a GFI outlet in the absence of a proper ground. Does any
electrician type have an opinion on that?
