Ah, I see.

I think it’s pretty verbose, but I think it would be good to have
“source …/etc/profile” appear at the *end* of the message.

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

If the last few lines give the most reliable hint (using “source”) I
think that would be most helpful.
