NixOS installer (flake + Lix)
=============================

1) Build is prewired with Lix; the installer ISO includes the repo at /etc/nixos.
2) Run the non-interactive Btrfs installer (set envs as needed):

   sudo DISK=/dev/vda HOSTNAME=nixos /etc/nixos/scripts/install-btrfs.sh

   Defaults: DISK=/dev/vda, HOSTNAME=nixos
   The script wipes the disk, creates Btrfs subvolumes (root, home, nix), copies the flake, generates hardware config, and installs with the chosen host name.

3) After install finishes, reboot into the new system.

Notes
- Filesystem is Btrfs with subvolumes: root, home, nix.
- The flake lives under /etc/nixos on the target; edit hosts/<hostname>.nix to customize.
