Replace old_installer.py with a curses TUI installer packaged as a one-file PyInstaller binary (python/installer/build.py, wrapped by python/installer/package.nix). The default .#installer is patched to run on foreign Linux live media; the new .#installer-nixos variant keeps its Nix store interpreter so it runs on NixOS. Add systems/iso, a minimal NixOS install CD with kernel 6.18 and ZFS 2.4 matching the deployed systems and the installer on PATH; build it with nix build .#iso. Shared logging and subprocess helpers move out of common.py into python/logging_config.py and python/process.py.

Installer ISO
Build a bootable NixOS ISO with the installer preinstalled:
nix build .#iso
Write result/iso/nixos-zfs-installer.iso to a USB stick (for example with dd) or boot it in a VM. The image is the minimal NixOS installation CD with ZFS enabled and nixos-installer on PATH, so once booted you can run:
sudo nixos-installer
The ISO bundles the .#installer-nixos package, a variant of the binary that keeps its Nix store linkage instead of being patched for foreign distributions.
Installer binary
Build the self-contained installer executable with:
nix build .#installer
The flake package (defined in python/installer/package.nix) uses the Python builder in python/installer/build.py, which stages only the installer modules before running PyInstaller. You can also call it directly when pyinstaller and patchelf are on PATH:
python -m python.installer.build --output ./nixos-installer
Copy result/bin/nixos-installer to the installer USB stick and run it as root from the NixOS live environment:
sudo ./nixos-installer
Validate the live environment first with:
./nixos-installer --check
Set ENCRYPT_KEY to enable LUKS during install:
sudo env ENCRYPT_KEY='change-me' ./nixos-installer
The binary bundles the Python runtime and only the installer modules it imports. It still expects the NixOS installer environment to provide system install tools such as parted, zfs, zpool, cryptsetup, nixos-generate-config, and nixos-install.
