Well, I do not know how to check.  Somehow, the ’sources.json’ should
contains the fixed-outputs substitutes in addition to the upstream
content.  And probably from both build farms.

It is something I wanted to do but I never took the time to complete
because it was not clear at the time how to compute the hash in
address.  Now fixed-output is cleared for me. :-)

It is not clear how to deal with packages into a ’computed-file’.  For
instance, etc/disarchive-manifest.scm create one store item per package
(somehow) then build a directory union.  Here the union is a file.
Well, it is not clear for me how to process.
