Depends on what kind of reproducibility we’re talking about.  It’s
simple to build bootstrap binaries:

  
https://www.gnu.org/software/guix/manual/html_node/Bootstrapping.html#Building-the-Bootstrap-Binaries

I think they are all bit-for-bit reproducible (that is, you can use
--rounds=3 and everything is fine), except for Guile due to
<http://bugs.gnu.org/20272>.)

However, if you build them today, you’ll 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,
