NixOS Supply Chain Contingency & Enterprise Governance Guide
Production-ready contingency migration manual for NixOS architects. Decouple from upstream Nixpkgs volatility with self-hosted Harmonia/Attic binary caches, automated flake pinning, private overlay governance, and zero-day patch pipelines.
The sudden dissolution of the Nixpkgs core maintenance team introduces urgent software supply chain and build-reproducibility risks for enterprise engineering teams. Infrastructure architects must rapidly transition to private package mirrors, audit upstream maintainer handoffs, and establish internal package governance to prevent CI/CD failures. This guide delivers a step-by-step contingency migration plan and fallback repository setup guide.
