+Subject: [PATCH 1/2] defn2[c|man]: don't rely on dpkg-architecture to set arch
+
+In yocto we'll always be cross compiling, and we'll always
+be building on linux for linux (vs. *BSD, hurd, etc.)
+
+Without this the arch is not detected, but it doesn't error
+out, and hence you get useless binaries that don't know any
+arch specific methods, and the end result will be strangeness
+like the loopback device not being configured/enabled.

+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:
