As a developer,
I want for Continuous Integration builds to be available in a public cache,
so that I may get the code running more easily.

implementation notes

this can be done safely using:

as per #155 (comment), we should have an isolated instance that will run builds on PRs, read-only accessing the main cache and not caching build results (or only between PR rebuilds), and another instance that runs builds on main and caches build results publicly.

@roberth > Do you have anything set up at least for NixOps4, the version of Nix you rely on, the providers, etc.? A cache somewhere that we could recommend in our README?

I've set up https://nixops4.cachix.org, written to by a Hercules CI agent that I run for the https://github.com/nixops4 org.

It's not a particularly long build, so I haven't bothered documenting the existence of this cache.

I don't think it's particularly relevant to Fediversity either, because a build will end up in the Fediversity cache anyway.

Indeed; but seeing as there is no Fediversity cache for now, that could give us a small gain in the meantime.
