NixOS install on DGX Spark

Disable Secure Boot

Update firmware

In the DGX OS (maybe possible to boot to recovery), run:

sudo fwupdmgr get-updates
sudo fwupdmgr update

Then maybe reboot is needed.

Set up boot config

Use releases from https://github.com/nix-community/nixos-images.

  • To get kernel arguments:

    curl -L https://github.com/nix-community/nixos-images/releases/download/nixos-26.05/netboot-aarch64-linux.ipxe

  • fetch kernel and initrd

    curl -L -o kernel https://github.com/nix-community/nixos-images/releases/download/nixos-26.05/Image-aarch64-linux \
        -o initrd https://github.com/nix-community/nixos-images/releases/download/nixos-26.05/initrd-aarch64-linux

  • copy them to /boot:

    sudo mkdir /boot/nixos
sudo cp -v kernel initrd /boot/nixos

  • edit GRUB config with sudo vim /boot/grub/grub.cfg, copy the first menuentry there, replace:

    • name with NixOS
    • id with nixos
    • kernel path with /boot/nixos/kernel
    • initrd path with /boot/nixos/initrd
    • kernel cmdline with the output from the first curl

Reboot into installer

  • tell GRUB to boot into this menuentry with sudo grub-reboot nixos
  • reboot
  • set up SSH authorized key or password for root using console

Install NixOS

I used nixos-anywhere, because I'm lazy:

nixos-anywhere --flake .#spark-805c --target-host spark-805c.local -L --build-on remote --phases disko,install,reboot
