Proxmox has been decommissioned in favor of NixOS running Incus for managing a homelab. The transition involved migrating from a multi-node Proxmox cluster to a declarative configuration using NixOS.

NixOS is valued for its deterministic and reproducible functional package manager, Nix. Users can construct and rebuild an entire operating system by inputting Nix DSL, allowing for incremental changes and precise control over the system.
