Setup

Ubuntu

• https://ubuntu.com/#download

Babashka

• https://github.com/babashka/babashka

bash < <(curl -s https://raw.githubusercontent.com/babashka/babashka/master/install)

Nix

Install Nix

Recommended install from https://nixos.org/download/

Note: This will request sudo

sh <(curl -L https://nixos.org/nix/install) --daemon

Enable "Experimental" features

Flakes support requires a feature flag to be set still.

mkdir -p ~/.config/nix
echo "experimental-features = nix-command flakes" > ~/.config/nix/nix.conf

Prelude

• https://github.com/bbatsov/prelude

curl -L https://git.io/epre | sh

Remote Deployment

Deploy to remote servers (edgenix and nasnix). All builds happen locally with nom for better progress display, then packages are copied to remote hosts.

Build Only (No Activation)

Build configurations locally to see what will be deployed:

# Build NixOS configs (no activation)
bb build-remote-os-edgenix
bb build-remote-os-nasnix

# Build home-manager configs (no activation)
bb build-remote-home-edgenix
bb build-remote-home-nasnix

Show Package Changes (Diff)

See what packages will change between current and new system (similar to nh local diffs):

# Show package changes for edgenix
bb diff-remote-os-edgenix

# Show package changes for nasnix
bb diff-remote-os-nasnix

Dry Run (See What Would Change)

Preview changes without applying them:

# See what would change on edgenix
bb dry-run-remote-os-edgenix

# See what would change on nasnix
bb dry-run-remote-os-nasnix

Switch (Build and Activate)

Build locally and activate on remote:

# Switch both NixOS and home-manager on both hosts
bb switch-remote

# Switch both NixOS and home-manager on specific host
bb switch-remote-edgenix
bb switch-remote-nasnix

# Switch only NixOS (builds with nom locally, then copies and activates remotely)
bb switch-remote-os-edgenix
bb switch-remote-os-nasnix

# Switch only home-manager (builds with nom locally, copies, then activates remotely)
bb switch-remote-home-edgenix
bb switch-remote-home-nasnix

How it works:

• NixOS: Builds with nom build locally, then uses nixos-rebuild switch --target-host to copy and activate
• Home-manager: Builds activation package with nom build locally, copies with nix copy, then activates remotely

Prerequisites:

• SSH key-based authentication set up for edgenix and nasnix
• Remote hosts accessible via their hostnames (configure ~/.ssh/config if needed)
• Remote hosts must have Nix installed and configured to accept SSH-based store access
• Remote user needs sudo access (tasks will prompt for sudo password when switching NixOS configurations)

Reboot

Restart the computer

sudo reboot
