Nanuqsaurus NixOS installer
===========================

Direct-from-URL install (wipes the whole disk)
---------------------------------------------

Pick a stable disk path (prefer /dev/disk/by-id/*) and run:

  sudo nix --experimental-features "nix-command flakes" \
    run github:nix-community/disko/latest#disko-install -- \
    --mode format \
    --flake "git+https://codeberg.org/<owner>/<repo>.git#nanuqsaurus-btrfs" \
    --disk main /dev/disk/by-id/<your-disk> \
    --mount-point /mnt

Adopt an existing NixOS install (no repartition)
-----------------------------------------------

Create a small local wrapper flake that imports this repo as a module and keeps
your machine’s `hardware-configuration.nix` for mounts/boot.

See: docs/adopt.md (on the custom ISO: `/etc/nixos/docs/adopt.md`)


ISO shortcut
------------

If you are using the custom ISO from this repo, it embeds the flake at /etc/nixos.
You can run the wrapper script (defaults: DISK=/dev/vda, TARGET_HOST=nanuqsaurus-btrfs):

  sudo /etc/nixos/scripts/install-btrfs.sh


Optionally set DISK, TARGET_HOST, and FLAKE:

  sudo DISK=/dev/disk/by-id/<your-disk> TARGET_HOST=nanuqsaurus-btrfs \
    FLAKE="git+https://codeberg.org/<owner>/<repo>.git" \
    /etc/nixos/scripts/install-btrfs.sh


This uses disko to create a GPT disk with a 550M EFI partition and a Btrfs partition
containing subvolumes root, home, and nix, mounted with compress=zstd.


After install finishes, reboot into the new system.
