Sort of.

I tried it out: When we have a source-substitute on our server,
everything is fine.

But I tried it with network connection shut down (don't know where we
do not have substitutes and was too lazy to configure firewall): Then
it tries git, fails. It then tries our substitute server and fails. But
that failure is again a stacktrace, and it doesn't try the SWH fallback.

So, maybe it works if the substitute server returns "I don't have
something", but I don't know how to try that out (Ok, I could add a new
package). But when it has a network error, it doesn't get back to the
last fallback.

What do you think?
