Flake-based NixOS config. Host: jupiter (ZimaBlade, NAS + services).

Structure

flake.nix                        # inputs + nixosConfigurations.jupiter
jupiter/configuration.nix        # system, users, ssh, samba, containers, caddy
jupiter/hardware-configuration.nix  # PLACEHOLDER — regenerate on real machine

First install (on the ZimaBlade)

1. Boot NixOS minimal ISO, partition + mount disks at /mnt.
2. Generate hardware config:

   sudo nixos-generate-config --root /mnt
   

   Copy /mnt/etc/nixos/hardware-configuration.nix into jupiter/.
3. Add your SSH public key to users.users.erik.openssh.authorizedKeys.keys.
4. Install:

   sudo nixos-install --flake .#jupiter
   

Rebuild after changes

sudo nixos-rebuild switch --flake .#jupiter

Remote from laptop:

nixos-rebuild switch --flake .#jupiter \
  --target-host erik@jupiter --use-remote-sudo

Adding a service

Copy the whoami block in oci-containers.containers, swap image/ports/volumes. Native NixOS module exists for many apps (Nextcloud, Jellyfin, Grafana...) — prefer services.<app> over a container when available.

Notes

• Backend is Podman with dockerCompat — docker CLI works, no daemon.
• Set correct time.timeZone and Samba path for your data mount.
• system.stateVersion = 26.05, install-time schema. Do NOT bump on upgrades.
