disko

Declarative disk partitioning

Adds the diskoConfigurations flake output.

When using disko with Flakes, the configuration is discovered first under the diskoConfigurations flake output attribute or else from the disko module of a NixOS configuration of that name under nixosConfigurations.

See disko README

Installation

To use these options, add to your flake inputs:

disko.url = "github:nix-community/disko";

and inside the mkFlake:

imports = [
  inputs.disko.flakeModules.default
];

Run nix flake lock and you're set.

Options

flake.diskoConfigurations

Instantiated Disko configurations. Used by disko and disko-install.

Type: lazy attribute set of raw value

Default: { }

Example:

{
  my-pc = {
    disko = {
      devices = {
        disk = {
          my-disk = {
            content = {
              partitions = {
                ESP = {
                  content = {
                    format = "vfat";
                    mountOptions = [
                      "umask=0077"
                    ];
                    mountpoint = "/boot";
                    type = "filesystem";
                  };
                  size = "500M";
                  type = "EF00";
                };
                root = {
                  content = {
                    format = "ext4";
                    mountpoint = "/";
                    type = "filesystem";
                  };
                  size = "100%";
                };
              };
              type = "gpt";
            };
            device = "/dev/sda";
            type = "disk";
          };
