Depends on what kind of reproducibility we=E2=80=99re talking about. It=E2= =80=99s simple to build bootstrap binaries: https://www.gnu.org/software/guix/manual/html_node/Bootstrapping.html#Bui= lding-the-Bootstrap-Binaries I think they are all bit-for-bit reproducible (that is, you can use --rounds=3D3 and everything is fine), except for Guile due to .) However, if you build them today, you=E2=80=99ll obviously get something different from the bootstrap binaries we currently use, which were from Guile 2.0.9, libc 2.19, GCC 4.7.2, some old Coreutils, etc. HTH, Ludo=E2=80=99.
