Why would the GFCI need to be placed upstream of the switch? I'd put it in a
box right where the U.F. leaves the building, on the load side of the switch

Could be rather awkward for periodic testing of the GFCI? A possible
problem is that the power feed to the lamp's switch does not have a
ground wire?


The GFCI needs to be placed upstream (ahead of) the switch which means
you might have to do a little detective work to see how the circuit is
routed. The idea here is to place it in an accessible location so
that you can test and reset the circuit when neccessary. If you are
lucky, you might just find that there is a duplex outlet upstream and
you can just replace it with an inexpensive GFCI and follow the wiring
diagram.

GFCIs are required to be grounded, if a ground is available, but they
are also allowed to be installed when there is not a sufficient
ground. In the latter case, a little sticker is placed on the outlet
that says "No Ground" or something similar.
