+Subject: [PATCH 2/2] inet[6].defn: fix inverted checks for loopback
+
+Compared to the hurd link.defn for loopback, we see these
+are inverted, meaning that you would only be able to configure
+a loopback device that was _not_ named "lo" (unlikely to exist).
+
+The result was that we'd update /run/network/ifstate for "lo"
+but never actually do anything for up/down, as shown below:
+
