Deinonyxus  

Deinonyxus is a personal spin of the UBlue Bluefin DX image with experimental Nix package manager baked in (borrowed from the great Daemonix image) and a first-login bootstrap for home-manager packages.

What’s inside

• Base: ghcr.io/ublue-os/bluefin-dx:latest without Cockpit, Docker, Firefox, VS Code
• Nix: multi-user install baked in; nix-overlay.service and nix-daemon.service enabled.
• First-login bootstrap: installs nix packages uv micro vscodium mc via home-manager.
• System packages added: syncthing, waydroid;
• System flatpaks added: Telegram Desktop, Waterfox

First login behavior

• Triggers for each non-root user on their first session.
• Writes state to ~/.local/state/deinonyxus/nixpkgs-init.done; delete it to rerun.
• Bootstraps ~/.config/home-manager/home.nix and runs home-manager switch with the package set above.
