Ah, I see.

I think it=E2=80=99s pretty verbose, but I think it would be good to have
=E2=80=9Csource =E2=80=A6/etc/profile=E2=80=9D appear at the *end* of the m=
essage.

(Guix generally produces a lot of output and in my experience people at
the MDC have learned to not read it=E2=80=A6 :-/)

If the last few lines give the most reliable hint (using =E2=80=9Csource=E2=
=80=9D) I
think that would be most helpful.
