+Since guix-daemon runs in a separate networking name space, the only
+interface available is "lo".  However its index is incremented by one
+at each build, so it can end up being greater than 255, leading to an
+assertion failure in 'find_ifname_and_index'.
+
+Work around that by directly querying the index of "lo".
