Thank you for the pointer. Good to see that the problem is almost addressed=
.
I will try to understand the discussion and see what is the status of
the proposed patch.

It is an half cooked solution because the Guix project cannot archive
all; for example in term of store resources.

The content-addressed mirror should be SWH, IMHO.

Well, once sources.json will be up, it should be almost done for the future=
.
But we still need to push all the correct sources that are on
ci.guix.gnu.org; at least all the url based source of package.

Do you have suggestion for a plan?

Thank you. This should fix the harfbuzz mismatch issue. Cool! :-)

Hum? I thought that I used ci.guix.gnu.org as substitutes... soI need to ch=
eck.
