Subject: substitute-binary fails when attempting to reconfigure

Running "guix system reconfigure" with substitutes enabled now
consistently fails for me with the following backtrace:

Running the same command with --no-substitutes works:

Running other commands including "guix system build" and "guix package"
with substitutes enabled works properly.

The 'guix' command being run here is using 'pre-inst-env' within a git
checkout that's on 9d297fa but with some local commits added including
'wip-http-pipelining'.  The 'guix-daemon' being run is from
guix-0.8.1.07157e8, which I suppose is using its own copy of 'guix
substitute' (right?).

This sounds possibly related to commit 41c45e7.

Yes, on GuixSD the daemon is using its own copy of ‘guix substitute’,
that is 07157e8.

So the problem could have to do with what the client passes with
‘set-build-options’, although I don’t know what’s going on.  Could you
try something like this:

       (or done? (process-stderr server)))))

This is fixed by commit 4d58122.

The problem was that for clients running as ‘root’, the
“substitute-urls” value that the client passes overrides that of the
daemon.  And the client’s default value was the empty list, which
‘substitute-binary’ currently rejects.

Thank you!

Ludo’.
