Hey #NixOS people and #linux self hosters. I'm curious to know if something like this already exists or should I make it.

1. I guess a DNS server locally that can look for requests to nix cache url, and redirects it to a local server

2. A service that catches this request (nginx I guess) and checks to see if the file exists locally, if it does, serve it, if not, download it then serve it.

Possible?

Hey everyone!
#Nix and #NixOS enable declarative systems and reproducible builds — topics that are especially interesting to the systems community.

I continue to be incredibly frustrated with how difficult it is to fabricate a test virtual machine from an arbitrary #NixOS configuration and have that test virtual machine actually match the real thing on basic details like the (virtualized) disk layout and filesystem mounts.

Maybe I'm doing something weird here, but basically all the tests I want to do before pulling the trigger on a real installation are invalidated by this semantic gap!
