Nanuqsaurus NixOS installer
|
||||
===========================
|
||||
|
||||
Run the non-interactive 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" \
|
||||
--disk main /dev/disk/by-id/<your-disk> \
|
||||
--mount-point /mnt
|
||||
|
||||
|
||||
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):
|
||||
|
||||
sudo /etc/nixos/scripts/install-btrfs.sh
|
||||
|
||||
|
||||
Optionally set DISK and TARGET_HOST (defaults: DISK=/dev/vda, TARGET_HOST=nanuqsaurus)
|
||||
Optionally set DISK, TARGET_HOST, and FLAKE:
|
||||
|
||||
sudo DISK=/dev/vda TARGET_HOST=nanuqsaurus /etc/nixos/scripts/install-btrfs.sh
|
||||
sudo DISK=/dev/disk/by-id/<your-disk> TARGET_HOST=nanuqsaurus \
|
||||
FLAKE="github:<owner>/<repo>" \
|
||||
/etc/nixos/scripts/install-btrfs.sh
|
||||
|
||||
|
||||
The script wipes the whole disk, creates Btrfs subvolumes (root, home, nix), copies the flake, generates hardware config, and installs. It writes host files under `/etc/nixos/hosts/local-<hostname>.nix` and `local-<hostname>-hardware.nix` (kept local to the machine).
|
||||
|
||||
|
||||
If you need a more custom setup please run the partitioning manually, mount the target to /mnt and then install the system:
|
||||
|
||||
nixos-install --root /mnt --flake "/mnt/etc/nixos#local-${TARGET_HOST}" --no-root-passwd
|
||||
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.
