Migrating from Proxmox to NixOS and Incus

The author migrated from Proxmox to NixOS with Incus after years of running a homelab, seeking a more reproducible and declarative infrastructure approach. While acknowledging Proxmox's capabilities, the author argues that its GUI-first design leads to state drift and configuration inconsistencies, particularly problematic when combined with AI agents making imperative fixes. NixOS's declarative configuration model allows the author to rebuild systems from version-controlled text files with guaranteed reproducibility, which proved the value of this approach when successfully migrating systems to new hardware.
