Formatting #

nixfmt hosts/laptop/configuration.nix

Hosts #

These are the target platforms which can be deployed using nixos-rebuild.

Laptop #

The active laptop configuration is hosts/laptop/configuration.nix, exposed as the laptop flake output:

sudo nixos-rebuild build --flake .#laptop
sudo nixos-rebuild test --flake .#laptop
sudo nixos-rebuild switch --flake .#laptop

Images #

These are configurations for building base NixOS images for the target platform.

Linode image #

Build a gzip'd disk image suitable for upload as a Linode custom image:

nix build .#linode-image-gz
linode-cli image-upload \
  --label "$(basename result/nixos-image-linode-*.img.gz | sed 's/-x86_64-linux\.img\.gz//')" \
  --region us-east result/nixos-image-linode-*.img.gz

The image uses linode/grub2 as the boot method. After uploading, update IMAGE in scripts/create-linode.sh with the new image ID. Configuration changes are deployed via nixos-rebuild --target-host, not by rebuilding the image.
