Host Inventory

  • Type: Reference
  • Status: Current
  • Scope: Managed hosts and staged NixOS targets
  • Canonical sources: flake.nix, hosts/*/default.nix, host hardware files, modules/common/default-config.nix, and potential/nova/default.nix
  • Last verified: Source commit 556df88494686003b1c4f20c8e0b99b5afc16a6e (2026-09-12); deployment evidence checked in Beszel on 2026-09-12
  • Review triggers: Changes under hosts/ or potential/, nixosConfigurations, nixosConfig.host, hardware imports, specialisations, release inputs, or host deployment state

This inventory describes each managed NixOS composition root and distinguishes declared configuration from live deployment evidence. Service ownership is summarised only to explain host purpose; the Service Catalogue owns the complete service-level inventory.

Registered NixOS hosts

Electra

Field Value
Role Laptop; primary desktop, gaming, local-AI, and mobile-work system
Hardware Framework Laptop 16, AMD AI 300-series platform, integrated AMD GPU, optional removable NVIDIA expansion bay
Location Mobile; deliberately no fixed nixosConfig.host.location
Release / state version Unstable (currently NixOS 26.11) / 25.11
Nebula 10.10.0.20
Inventory tags laptop, amdcpu, amdgpu, nvidiagpu, ollama
Auto-update Consumer

Electra has one flake target and three boot variants in every generation. The base entry is labelled battery; igpu and dgpu are specialisations. They describe whether the removable NVIDIA expansion bay is physically absent or present, not a preference for which GPU to use. The base configuration owns shared hardware and endurance behavior; the specialisations relax that endurance policy, add gaming, maker, and local-Ollama workloads, and in dgpu add the NVIDIA hardware configuration. ADR-001 records why these variants are one generation and why the GPU variants describe hardware presence.

Lena

Field Value
Role Laptop for Claire, with a second administrator account
Hardware Lenovo IdeaPad 5 2-in-1 Gen 9 (16AHP9 hardware module), AMD CPU/GPU, tablet sensors, fingerprint reader
Location Mobile; deliberately no fixed nixosConfig.host.location
Release / state version Unstable (currently NixOS 26.11) / 25.11
Nebula 10.10.0.21
Inventory tags laptop, amdcpu, amdgpu
Auto-update Consumer

Lena uses the laptop and AI desktop profiles, supports tablet-mode sensors, and limits SSH to the Nebula interface. It has no hardware specialisations.

Vega

Field Value
Role Headless storage-backed services, AI agents, and cache server
Hardware Physical Intel server with Intel graphics support and a persistent secondary Btrfs SSD
Location Desk
Release / state version Unstable (currently NixOS 26.11) / 25.11
Nebula 10.10.0.2
Inventory tags server, intelcpu, docker, attic
Auto-update Consumer

Vega is the main storage-backed application host. It also provides selected fleet functions including Attic, AI-agent integrations, Engram Cloud, Trilium, BookStack, mesh DNS/exit-node behavior, and native services backed by local or NAS state. Its secondary SSD at /mnt/storage and /mnt/partial deliberately survives OS reprovisioning and is managed outside Disko.

Lyra

Field Value
Role Headless GPU compute and media/service server
Hardware Intel i5-1340P system with integrated Intel graphics and a permanently attached Thunderbolt NVIDIA RTX 4070 eGPU
Location Desk, physically on top of Vega
Release / state version Unstable (currently NixOS 26.11) / 25.11
Nebula 10.10.0.3
Inventory tags server, intelcpu, nvidiagpu, docker, ollama, media, attic
Auto-update Consumer

Lyra owns GPU-heavy and media workloads. The RTX 4070 is compute-only; the integrated Intel GPU is also available to media processing. Current configuration includes native Ollama, Redview, Jellyfin, Immich, Tdarr, and Whisper capabilities alongside retained container support.

Cosmos

Field Value
Role Stable PostgreSQL server VM with Adminer
Hardware Proxmox/QEMU virtual machine without configured swap
Location pve2
Release / state version Stable NixOS 26.05 / 26.05
Nebula 10.10.0.8
Inventory tags server, postgresql, adminer, proxmox, nebula
Auto-update Consumer

PostgreSQL and Adminer bind to the Nebula address rather than a LAN-wide listener. Cosmos also produces logical PostgreSQL backups. Application-specific database contracts live alongside its host configuration.

Chaos

Field Value
Role Stable Docker workload VM for packages not suitable for native service packaging
Hardware Proxmox/QEMU virtual machine without configured swap
Location pve2
Release / state version Stable NixOS 26.05 / 26.05
Nebula 10.10.0.9
Inventory tags server, docker, proxmox, nebula, awkward-packages
Auto-update Consumer

Chaos isolates container-oriented workloads from the physical service hosts. Its declared workloads include Rangarr, Killarr, the Paseo relay and web UI, slskd, SynthSeek, and Plexdrome. Individual service entries must distinguish enabled configuration from dormant or transitional runtime state.

Staged host: Nova

Nova is a Framework Desktop with an AMD Ryzen AI Max+ 395 platform. Its proposed NixOS configuration lives under potential/nova/, is not imported by flake.nix, and is not built by normal flake checks or fleet CI. The file proposes AMD/ROCm Ollama, Docker, and an auto-update producer role.

Beszel reported Fedora 44 on Nova on 2026-09-12. Until a NixOS deployment is explicitly completed and verified, treat everything in potential/nova/ as future intent rather than an active NixOS capability.

Inventory semantics

  • role, purpose, optional location, and tags come from evaluated nixosConfig.host values.
  • Tags are filterable inventory facts. They must not be moved to system.nixos.tags, which would alter boot-generation labels.
  • system.stateVersion protects compatibility defaults; it is not the installed NixOS release.
  • Release values above record the inputs evaluated on the verification date and will change as channels advance.
  • Live online/offline state belongs in monitoring, not this page.
