Virby is a module for nix-darwin that configures a lightweight linux VM as a remote build machine for nix, allowing linux packages to be built on macOS.

What is the advantage of this over the inbuilt linux-builder in nix-darwin[1]?

I assume it being vfkit based might make it more performant? Are there any benchmarks comparing them?
