Hosts

All NixOS hosts are managed declaratively via flakes. Each host has its own directory under hosts/nixos/. Darwin hosts live under hosts/darwin/. Standalone home-manager configs live under hosts/home/.

NixOS Hosts

Darwin Hosts

Host	Arch	Role

Templates

Host	Purpose
anywhere	Generic NixOS server template for nixos-anywhere
virt-x86_64	VM testing (x86_64)
virt-aarch64	VM testing (aarch64)

Standalone Home Configs

Config	User	Modules
hosts/home/nikhil.nix	nikhil	default, ai, stylix (cli-only), git with Juspay conditional email
hosts/home/admin.nix	(current)	default, home-only

Common Config

Workstations (semi, dsd) share hosts/nixos/common/workstation.nix which imports:

• base (nixosModules.default)
• juspay (nixosModules.juspay) - workspace config (zsh, openssh, docker, tailscale, postgres, redis)
• sops-nix for secrets
• disko for disk management
• Beszel agent
• Tailscale
• Virtualisation (docker + podman)
• FileBrowser Quantum

It also wires:

• The nikhil.singh user (from config.nix, Juspay identity) with wheel/docker/networkmanager groups
• sops age key at ~/.config/sops/age/keys.txt, default file secrets/office.yaml
• Tailscale auth key from sops
• Beszel agent as user (rootless Docker) with token from sops
• FileBrowser password from sops
• nix access token from sops (via !include in nix.extraOptions)
• SSH known hosts for dsd + semi (cross-building)

Each host then overrides or extends as needed (e.g., mach adds media mount, obox adds hub services, dsd adds minecraft).
