If you mean after system reconfiguring, then it is expected, because
nothing has changed, you just moved package definitions from you system
config to another file, so that "guix build" and other commands could
see these packages.

Or do you mean after modifying
"/sys/module/firmware_class/parameters/path" and "insmod"-ing that
firmware?

Here is an excerpt of Ludo's message.  Please report after doing these
steps.
