>From my side, what I would like to achieve soon:

 1- compute sources.json by CI, which means turn the current code as derivation;
 2- add the Guix fixed-output substitutes in the list of upstream.

But how to do #1 is not clear for me.  And I have never tried this #2.

Then what is also missing is:

 3- have a collection of sources.json per Guix revision -- at least
some determined by us;
 4- make the SWH nixguix loader points to this collection.

Currently, the file 'sources.json' contains the field 'revision' which
is the Guix revision (commit).  What is not clear is if the collection
is by appending or via different files.  It is a pending discussion
with SWH folks, IIRC.
