···- `nixos-rebuild-ng`, a full rewrite of `nixos-rebuild` in Python, is available for testing. You can enable it by setting [system.rebuild.enableNg](options.html#opt-system.rebuild.enableNg) in your configuration (this will replace the old `nixos-rebuild`), or by adding `nixos-rebuild-ng` to your `environment.systemPackages` (in this case, it will live side-by-side with `nixos-rebuild` as `nixos-rebuild-ng`). It is expected that the next major version of NixOS (25.11) will enable `system.rebuild.enableNg` by default.<!-- To avoid merge conflicts, consider adding your item at an arbitrary place in the list instead. -->···- `nodePackages.stackdriver-statsd-backend` has been removed, as the StackDriver service has been discontinued by Google, and therefore the package no longer works.- `python3Packages.opentracing` has been removed due to being unmaintained upstream. [OpenTelemetry](https://opentelemetry.io/) is the recommended replacement.

It is expected that the next major version of NixOS (25.11) will enable `system.rebuild.enableNg` by default.+It allows users to build platform-specific (disk) images from their NixOS configurations. `nixos-rebuild build-image` works similar to the popular [nix-community/nixos-generators](https://github.com/nix-community/nixos-generators) project. See new [section on image building in the nixpkgs manual](https://nixos.org/manual/nixpkgs/unstable/#sec-image-nixos-rebuild-build-image).<!-- To avoid merge conflicts, consider adding your item at an arbitrary place in the list instead. -->···- `nodePackages.stackdriver-statsd-backend` has been removed, as the StackDriver service has been discontinued by Google, and therefore the package no longer works.- `python3Packages.opentracing` has been removed due to being unmaintained upstream. [OpenTelemetry](https://opentelemetry.io/) is the recommended replacement.+- Default file names of images generated by several builders in `system.build` have been changed as outlined in the table below.+Names are now known at evaluation time and customizable via the new options `image.baseName`, `image.extension`, `image.fileName` and `image.filePath` with the latter returning a path relative to the derivations out path (e.g. `iso/${image.fileName` for iso images).+|--------------------------+------------------------------------------------------------+-----------------------------------------------------------------|+| amazonImage | nixos-amazon-image-25.05pre-git-x86_64-linux.vhd | nixos-image-amazon-25.05pre-git-x86_64-linux.vhd |+| digitalOceanImage | nixos.qcow2.gz | nixos-image-digital-ocean-25.05pre-git-x86_64-linux.qcow2.gz |+| googleComputeImage | nixos-image-25.05pre-git-x86_64-linux.raw.tar.gz | nixos-image-google-compute-25.05pre-git-x86_64-linux.raw.tar.gz |+| hypervImage | nixos-25.05pre-git-x86_64-linux.vhdx | nixos-image-hyperv-25.05pre-git-x86_64-linux.vhdx |+| isoImage (installer) | nixos-25.05pre-git-x86_64-linux.iso | nixos-image-25.05pre-git-x86_64-linux.iso |+| linodeImage | nixos-image-25.05pre-git-x86_64-linux.img.gz | nixos-image-linode-25.05pre-git-x86_64-linux.img.gz |+| metadata (lxc-container) | nixos-system-x86_64-linux.tar.xz | nixos-image-lxc-metadata-25.05pre-git-x86_64-linux.tar.xz |+| openstackImage (zfs) | nixos-openstack-image-25.05pre-git-x86_64-linux.root.qcow2 | nixos-image-openstack-zfs-25.05pre-git-x86_64-linux.root.qcow2 |+| sdImage | nixos-sd-image-25.05pre-git-x86_64-linux.img.zst | nixos-image-sd-card-25.05pre-git-x86_64-linux.img.zst |+| tarball (lxc-container) | nixos-system-x86_64-linux.tar.xz | nixos-image-lxc-25.05pre-git-x86_64-linux.tar.xz |+| tarball (proxmox-lxc) | nixos-system-x86_64-linux.tar.xz | nixos-image-lxc-proxmox-25.05pre-git-x86_64-linux.tar.xz |+| vagrantVirtualbox | nixos-25.05pre-git-x86_64-linux.ova | nixos-image-virtualbox-25.05pre-git-x86_64-linux.ova |+| virtualBoxOVA | virtualbox-vagrant.box | nixos-image-vagrant-virtualbox-25.05pre-git-x86_64-linux.ova |+| vmwareImage | nixos-25.05pre-git-x86_64-linux.vmdk | nixos-image-vmware-25.05pre-git-x86_64-linux.vmdk |
