Pushing to nix-serve

[DieracDelta]

Suppose I build package A on my computer and want to push it to the cache. With cachix, I would do nix build $REPO | cachix push $CACHE_NAME. Any idea how to achieve something similar with nix-serve? I don't see mention of this in the docs.

This may be a bit late but you can always copy the result with nix copy and nix-copy-closure. This ofc requires your builder to have write access to the nix store of the cache.
