Replace the hardcoded list of systems in flake.nix with automatic discovery of host directories under ./systems, and generate the CI build matrix dynamically by evaluating nixosConfigurations rather than maintaining a duplicate list in the workflow.

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. SSH is enabled and the nixos and root accounts use the password nixos, so you can also run the installer remotely. Once booted:
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
Paste a value into the TUI encryption password field to enable LUKS during install, or set ENCRYPT_KEY:
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.
