+@unnumberedsubsec Reducing the Set of Bootstrap Binaries
+
+Our bootstrap binaries currently include GCC, Guile, etc. That's a lot
+of binary code! Why is that a problem? It's a problem because these
+big chunks of binary code are practically non-auditable, which makes it
+hard to establish what source code produced them. Every unauditable
+binary also leaves us vulnerable to compiler backdoors as described by
+Ken Thompson in the 1984 paper @emph{Reflections on Trusting Trust}.
+
+This is mitigated by the fact that our bootstrap binaries were generated
+from an earlier Guix revision. Nevertheless it lacks the level of
+transparency that we get in the rest of the package dependency graph,
+where Guix always gives us a source-to-binary mapping. Thus, our goal
+is to reduce the set of bootstrap binaries to the bare minimum.
+
+The @uref{http://bootstrappable.org, Bootstrappable.org web site} lists
+on-going projects to do that. One of these is about replacing the
+bootstrap GCC with a sequence of assemblers, interpreters, and compilers
+of increasing complexity, which could be built from source starting from
+a simple and auditable assembler. Your help is welcome!
