FYI,

I believe that no one has yet managed a reproducible build of bitcoin-knots on power 9.  Bitcoin-knots has a script to reproducibly build itself via guix on x86_64: "$bitcoin-knots-src/contrib/guix/guix-build". The lead developer told me, "'guix-build' is only known to work reproducibly on x86_64 at the moment; I don't know the outcome on POWER9".

An older bit of documentation says the same thing, "Requirements
Conservatively, you will need an *x86_64 machine* with:"

https://github.com/bitcoinknots/bitcoin/blob/v23.0.knots20220529/contrib/guix/README.md

This newer file does not say that you need an x86_64 machine:

Thanks,

Joshua
