   Passing ADDITIONAL_GUIX_COMMON_FLAGS="--no-substitutes --bootstrap" as suggested doesn't work:

         ...outputting in: '/bitcoin/guix-build-a1f0b8b62eb8/output/x86_64-linux-gnu'
             ...bind-mounted in container to: '/outdir-base/x86_64-linux-gnu'
   guix time-machine: error: bootstrap: unrecognized option
   

   and I think bootstrapping is more than covered in the preceding "Choose your security model" section.

   I agree the Choose Your Security Model section sufficiently explains bootstrapping. The text removed in this PR seems redundant.
