Could you share how you generated the profile ’my-profile’?

Well, I am missing what you want to achieve.

The profile used by ’pull’, by default ~/.config/guix/current, is
somehow special compared to other profiles as ~/.guix-profile.

Compare:

    cat ~/.config/guix/current/manifest | grep -E '(source|provenance)'
    cat ~/.guix-profile/manifest        | grep -E '(source|provenance)'

It is my understanding and maybe someone will correct me: 'source is the
“properties“ tracking the channels from where the “pull” comes and
'provenance is the “properties” tracking the channel from where the
packages come from.

Well, 'source is used by “guix describe” but 'provenance is not used––it
is by “guix pack --save-provenance” but that’s another story.

Report where?

Hope that helps,
