This all takes place in (guix scripts offload) and should be relatively easy to modify (see commit 5ef9d7deeab348e0f714f91a3c02ce4b72bbe3c1 for an example). [Time passes…] I thought it would be quicker to fix it but was proved wrong, because ‘guix substitute’ expects to be able to pass non-file ports to ‘decompressed-ports’, which means we cannot just use ‘duplicate-port’ there. Anyway, I’ve pushed ‘wip-offload-compression’ and we’ll look at it again after the release. Thanks, Ludo’.
