This is correct. Back then we ran into trouble with our Guix installation at work when someone modified permission bits on the bootstrap binaries, causing a rebuild of everything. It took us a while to find out the cause and revert the change. Some of the bootstrap binaries can be reproduced from source (if you make sure to follow the Guix recipes), but others (like Guile IIRC) don’t have reproducible build systems, so reproducing the exact same binaries without using Guix is going to be very challenging. I don’t know if it is possible and if it would make sense to cheat, i.e. just lie to Guix about the hashes of the bootstrap binaries. ~~ Ricardo
