NixOS has been successfully optimized to run on as little as 512MB RAM, idling at just 96MB with only 54 kernel modules loaded. A full channel update and rebuild including a kernel switch completes within 512MB with a 371MB peak, down from initial 288MB idle and OOM issues during rebuilds.
Background
NixOS is a Linux distribution known for its declarative configuration and reproducible builds, but traditionally requires significant resources. This guide demonstrates aggressive optimization techniques for low-end VPS environments.
