can we please consider to add a specific section to the manual including
a properly redacted copy of this exact text?

I think that specifically stating that no non-free code will be saved in
store due to ``guix build`` is specifically addressed by the snippet
field in <origin> (other procedures?) *and* assessed [1] by guix
maintainers will be of great help in all future discussions on this
topic (and there will be other discussions :-) )

WDYT?

David whould you like to propose a patch if anouth consensus on this
topic is reached? If you cannot, I can help on this.


Thanks! Gio'



[1] it means that missing to remove non-free code is considered a bug
and treated accordingly to the FSGD
