Well, if we disagree here then it is rare enough to be notified. Or
maybe we miscommunicate. :-)

I was meaning ’signed commit’ as authentication.
I do not see how signed commits prevent hostile code; because this
hostile code must be pushed to the Gitlab instance in the first place.
Signed commit acts as “double-authentication” for authenticating the
person responsible of the commit. The attacker needs to control two
“channels“ of “communication”: the remote Git server and the local GPG
thing.
I agree signed commits is necessary for Guix itself or else but I am not
convinced of its interest for guix-past.
As shown elsewhere in the thread, just a channel configuration where the
introduction is not noticed and then “guix pull” is happy.
And I am not convinced that the regular scientists really take care
about these subtleties of GPG. Obviously, that’s not an argument. ;-)
I restate that signed commits (authentication) add more burden for the
channel guix-past than it solves concrete issues.
Maybe we do not share the same point of view of this topic. :-)
Cheers,
simon
