-about: A package that does not produce a bit-by-bit reproducible result each time it is built
-title: ''
-labels: [ '0.kind: enhancement', '6.topic: reproducible builds' ]
-assignees: ''
-
----
-
-Building this package twice does not produce the bit-by-bit identical result each time, making it harder to detect CI breaches. You can read more about this at https://reproducible-builds.org/ .
-
-Fixing bit-by-bit reproducibility also has additional advantages, such as avoiding hard-to-reproduce bugs, making content-addressed storage more effective and reducing rebuilds in such systems.
-
-### Steps To Reproduce
-
-```
-nix-build '<nixpkgs>' -A ... --check --keep-failed
-```
-
-You can use `diffoscope` to analyze the differences in the output of the two builds.
-
-To view the build log of the build that produced the artifact in the binary cache:
-
-```
-nix-store --read-log $(nix-instantiate '<nixpkgs>' -A ...)
-```
-
-### Additional context
-
-(please share the relevant fragment of the diffoscope output here,
-and any additional analysis you may have done)

 ## Writing good commit messages
 
 In addition to writing properly formatted commit messages, it's important to include relevant information so other developers can later understand *why* a change was made. While this information usually can be found by digging code, mailing list/Discourse archives, pull request discussions or upstream changes, it may require a lot of work.
 
-Package version upgrades usually allow for simpler commit messages, including attribute name, old and new version, as well as a reference to the relevant release notes/changelog. Every once in a while a package upgrade requires more extensive changes, and that subsequently warrants a more verbose message.
-
-Pull requests should not be squash merged in order to keep complete commit messages and GPG signatures intact and must not be when the change doesn't make sense as a single commit.
-This means that, when addressing review comments in order to keep the pull request in an always mergeable status, you will sometimes need to rewrite your branch's history and then force-push it with `git push --force-with-lease`.
-Useful git commands that can help a lot with this are `git commit --patch --amend` and `git rebase --interactive`. For more details consult the git man pages or online resources like [git-rebase.io](https://git-rebase.io/) or [The Pro Git Book](https://git-scm.com/book/en/v2/Git-Tools-Rewriting-History).
-
-## Rebasing between branches (i.e. from master to staging)
-
-From time to time, changes between branches must be rebased, for example, if the
-number of new rebuilds they would cause is too large for the target branch. When
-rebasing, care must be taken to include only the intended changes, otherwise
-many CODEOWNERS will be inadvertently requested for review.  To achieve this,
-rebasing should not be performed directly on the target branch, but on the merge
-base between the current and target branch.
-
-In the following example, we assume that the current branch, called `feature`,
-is based on `master`, and we rebase it onto the merge base between
-`master` and `staging` so that the PR can eventually be retargeted to
-`staging` without causing a mess. The example uses `upstream` as the remote for `NixOS/nixpkgs.git`
-while `origin` is the remote you are pushing to.
-
-
-```console
-# Rebase your commits onto the common merge base
-git rebase --onto upstream/staging... upstream/master
-# Force push your changes
-git push origin feature --force-with-lease
-```
-
-The syntax `upstream/staging...` is equivalent to `upstream/staging...HEAD` and
-stands for the merge base between `upstream/staging` and `HEAD` (hence between
-`upstream/staging` and `upstream/master`).
-
-Then change the base branch in the GitHub PR using the *Edit* button in the upper
-right corner, and switch from `master` to `staging`. *After* the PR has been
-retargeted it might be necessary to do a final rebase onto the target branch, to
-resolve any outstanding merge conflicts.
-
-```console
-# Rebase onto target branch
-git rebase upstream/staging
-# Review and fixup possible conflicts
-git status
-# Force push your changes
-git push origin feature --force-with-lease
-```
+For package version upgrades and such a one-line commit message is usually sufficient.
 
 ## Backporting changes
 
 Follow these steps to backport a change into a release branch in compliance with the [commit policy](https://nixos.org/nixpkgs/manual/#submitting-changes-stable-release-branches).
 
-You can add a label such as `backport release-23.05` to a PR, so that merging it will
-automatically create a backport (via [a GitHub Action](.github/workflows/backport.yml)).
-This also works for pull requests that have already been merged, and might take a couple of minutes to trigger.
-
-You can also create the backport manually:
-
 1. Take note of the commits in which the change was introduced into `master` branch.
-2. Check out the target _release branch_, e.g. `release-23.05`. Do not use a _channel branch_ like `nixos-23.05` or `nixpkgs-23.05-darwin`.
+2. Check out the target _release branch_, e.g. `release-20.09`. Do not use a _channel branch_ like `nixos-20.09` or `nixpkgs-20.09`.
 3. Create a branch for your change, e.g. `git checkout -b backport`.
 4. When the reason to backport is not obvious from the original commit message, use `git cherry-pick -xe <original commit>` and add a reason. Otherwise use `git cherry-pick -x <original commit>`. That's fine for minor version updates that only include security and bug fixes, commits that fixes an otherwise broken package or similar. Please also ensure the commits exists on the master branch; in the case of squashed or rebased merges, the commit hash will change and the new commits can be found in the merge message at the bottom of the master pull request.
-5. Push to GitHub and open a backport pull request. Make sure to select the release branch (e.g. `release-23.05`) as the target branch of the pull request, and link to the pull request in which the original change was committed to `master`. The pull request title should be the commit title with the release version as prefix, e.g. `[23.05]`.

The pull request title should be the commit title with the release version as prefix, e.g. `[20.09]`.
 6. When the backport pull request is merged and you have the necessary privileges you can also replace the label `9.needs: port to stable` with `8.has: port to stable` on the original pull request. This way maintainers can keep track of missing backports easier.

 # Fetchers {#chap-pkgs-fetchers}
 
-Building software with Nix often requires downloading source code and other files from the internet.
-`nixpkgs` provides *fetchers* for different protocols and services. Fetchers are functions that simplify downloading files.
+When using Nix, you will frequently need to download source code and other files from the internet. For this purpose, Nix provides the [_fixed output derivation_](https://nixos.org/manual/nix/stable/#fixed-output-drvs) feature and Nixpkgs provides various functions that implement the actual fetching from various protocols and services.
 
-## Caveats {#chap-pkgs-fetchers-caveats}
+## Caveats
 
-Fetchers create [fixed output derivations](https://nixos.org/manual/nix/stable/#fixed-output-drvs) from downloaded files.
-Nix can reuse the downloaded files via the hash of the resulting derivation.
+Because fixed output derivations are _identified_ by their hash, a common mistake is to update a fetcher's URL or a version parameter, without updating the hash. **This will cause the old contents to be used.** So remember to always invalidate the hash argument.
 
-The fact that the hash belongs to the Nix derivation output and not the file itself can lead to confusion.
-For example, consider the following fetcher:
-
-```nix
-fetchurl {
-  url = "http://www.example.org/hello-1.0.tar.gz";
-  hash = "sha256-lTeyxzJNQeMdu1IVdovNMtgn77jRIhSybLdMbTkf2Ww=";
-};
-```
-
-A common mistake is to update a fetcher’s URL, or a version parameter, without updating the hash.
-
-```nix
-fetchurl {
-  url = "http://www.example.org/hello-1.1.tar.gz";
-  hash = "sha256-lTeyxzJNQeMdu1IVdovNMtgn77jRIhSybLdMbTkf2Ww=";
-};
-```
-
-**This will reuse the old contents**.
-Remember to invalidate the hash argument, in this case by setting the `hash` attribute to an empty string.
-
-```nix
-fetchurl {
-  url = "http://www.example.org/hello-1.1.tar.gz";
-  hash = "";
-};
-```
-
-Use the resulting error message to determine the correct hash.
-
-```
-error: hash mismatch in fixed-output derivation '/path/to/my.drv':
-         specified: sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=
-            got:    sha256-lTeyxzJNQeMdu1IVdovNMtgn77jRIhSybLdMbTkf2Ww=
-```
-
-A similar problem arises while testing changes to a fetcher's implementation. If the output of the derivation already exists in the Nix store, test failures can go undetected. The [`invalidateFetcherByDrvHash`](#tester-invalidateFetcherByDrvHash) function helps prevent reusing cached derivations.
+For those who develop and maintain fetchers, a similar problem arises with changes to the implementation of a fetcher. These may cause a fixed output derivation to fail, but won't normally be caught by tests because the supposed output is already in the store or cache. For the purpose of testing, you can use a trick that is embodied by the [`invalidateFetcherByDrvHash`](#sec-pkgs-invalidateFetcherByDrvHash) function. It uses the derivation `name` to create a unique output path per fetcher implementation, defeating the caching precisely where it would be harmful.
 
 ## `fetchurl` and `fetchzip` {#fetchurl}
 
-Two basic fetchers are `fetchurl` and `fetchzip`. Both of these have two required arguments, a URL and a hash. The hash is typically `hash`, although many more hash algorithms are supported. Nixpkgs contributors are currently recommended to use `hash`. This hash will be used by Nix to identify your source. A typical usage of `fetchurl` is provided below.

-The main difference between `fetchurl` and `fetchzip` is in how they store the contents. `fetchurl` will store the unaltered contents of the URL within the Nix store. `fetchzip` on the other hand, will decompress the archive for you, making files and directories directly accessible in the future. `fetchzip` can only be used with archives. Despite the name, `fetchzip` is not limited to .zip files and can also be used with any tarball.
-
-## `fetchpatch` {#fetchpatch}
-
-`fetchpatch` works very similarly to `fetchurl` with the same arguments expected. It expects patch files as a source and performs normalization on them before computing the checksum. For example, it will remove comments or other unstable parts that are sometimes added by version control systems and can change over time.
-
-- `relative`: Similar to using `git-diff`'s `--relative` flag, only keep changes inside the specified directory, making paths relative to it.
-- `stripLen`: Remove the first `stripLen` components of pathnames in the patch.
-- `decode`: Pipe the downloaded data through this command before processing it as a patch.
-- `extraPrefix`: Prefix pathnames by this string.
-- `excludes`: Exclude files matching these patterns (applies after the above arguments).
-- `includes`: Include only files matching these patterns (applies after the above arguments).
-- `revert`: Revert the patch.
-
-Note that because the checksum is computed after applying these effects, using or modifying these arguments will have no effect unless the `hash` argument is changed as well.

For example it will remove comments or other unstable parts that are sometimes added by version control systems and can change over time.
 
 Most other fetchers return a directory rather than a single file.

-`fetchFromGitea` expects five arguments. `domain` is the gitea server name. `owner` is a string corresponding to the Gitea user or organization that controls this repository. `repo` corresponds to the name of the software repository. These are located at the top of every Gitea HTML page as `owner`/`repo`. `rev` corresponds to the Git commit hash or tag (e.g `v1.0`) that will be downloaded from Git. Finally, `hash` corresponds to the hash of the extracted directory. Again, other hash algorithms are also available but `hash` is currently preferred.

-# pkgs.mkBinaryCache {#sec-pkgs-binary-cache}
-
-`pkgs.mkBinaryCache` is a function for creating Nix flat-file binary caches. Such a cache exists as a directory on disk, and can be used as a Nix substituter by passing `--substituter file:///path/to/cache` to Nix commands.
-
-Nix packages are most commonly shared between machines using [HTTP, SSH, or S3](https://nixos.org/manual/nix/stable/package-management/sharing-packages.html), but a flat-file binary cache can still be useful in some situations. For example, you can copy it directly to another machine, or make it available on a network file system. It can also be a convenient way to make some Nix packages available inside a container via bind-mounting.
-
-Note that this function is meant for advanced use-cases. The more idiomatic way to work with flat-file binary caches is via the [nix-copy-closure](https://nixos.org/manual/nix/stable/command-ref/nix-copy-closure.html) command. You may also want to consider [dockerTools](#sec-pkgs-dockerTools) for your containerization needs.
-
-## Example {#sec-pkgs-binary-cache-example}
-
-The following derivation will construct a flat-file binary cache containing the closure of `hello`.
-
-```nix
-mkBinaryCache {
-  rootPaths = [hello];
-}
-```
-
-- `rootPaths` specifies a list of root derivations. The transitive closure of these derivations' outputs will be copied into the cache.
-
-Here's an example of building and using the cache.
-
-Build the cache on one machine, `host1`:
-
-```shellSession
-nix-build -E 'with import <nixpkgs> {}; mkBinaryCache { rootPaths = [hello]; }'
-```
-
-```shellSession
-/nix/store/cc0562q828rnjqjyfj23d5q162gb424g-binary-cache
-```
-
-Copy the resulting directory to the other machine, `host2`:
-
-```shellSession
-scp result host2:/tmp/hello-cache
-```
-
-Substitute the derivation using the flat-file binary cache on the other machine, `host2`:
-```shellSession
-nix-build -A hello '<nixpkgs>' \
-  --option require-sigs false \
-  --option trusted-substituters file:///tmp/hello-cache \
-  --option substituters file:///tmp/hello-cache

-
-`command` _optional_
-
-: Run this command in the environment of the derivation, in an interactive shell. See the `--command` option in the [`nix-shell` documentation](https://nixos.org/manual/nix/stable/command-ref/nix-shell.html?highlight=nix-shell#options).

-# `<nixpkgs/nixos/lib/make-disk-image.nix>` {#sec-make-disk-image}
-
-`<nixpkgs/nixos/lib/make-disk-image.nix>` is a function to create _disk images_ in multiple formats: raw, QCOW2 (QEMU), QCOW2-Compressed (compressed version), VDI (VirtualBox), VPC (VirtualPC).
-
-This function can create images in two ways:
-
-- using `cptofs` without any virtual machine to create a Nix store disk image,
-- using a virtual machine to create a full NixOS installation.
-
-When testing early-boot or lifecycle parts of NixOS such as a bootloader or multiple generations, it is necessary to opt for a full NixOS system installation.
-Whereas for many web servers, applications, it is possible to work with a Nix store only disk image and is faster to build.
-
-NixOS tests also use this function when preparing the VM. The `cptofs` method is used when `virtualisation.useBootLoader` is false (the default). Otherwise the second method is used.
-
-## Features {#sec-make-disk-image-features}
-
-For reference, read the function signature source code for documentation on arguments: <https://github.com/NixOS/nixpkgs/blob/master/nixos/lib/make-disk-image.nix>.
-Features are separated in various sections depending on if you opt for a Nix-store only image or a full NixOS image.
-
-### Common {#sec-make-disk-image-features-common}
-
-- arbitrary NixOS configuration
-- automatic or bound disk size: `diskSize` parameter, `additionalSpace` can be set when `diskSize` is `auto` to add a constant of disk space
-- multiple partition table layouts: EFI, legacy, legacy + GPT, hybrid, none through `partitionTableType` parameter
-- OVMF or EFI firmwares and variables templates can be customized
-- root filesystem `fsType` can be customized to whatever `mkfs.${fsType}` exist during operations
-- root filesystem label can be customized, defaults to `nix-store` if it's a Nix store image, otherwise `nixpkgs/nixos`
-- arbitrary code can be executed after disk image was produced with `postVM`
-- the current nixpkgs can be realized as a channel in the disk image, which will change the hash of the image when the sources are updated
-- additional store paths can be provided through `additionalPaths`
-
-### Full NixOS image {#sec-make-disk-image-features-full-image}
-
-- arbitrary contents with permissions can be placed in the target filesystem using `contents`
-- a `/etc/nixpkgs/nixos/configuration.nix` can be provided through `configFile`
-- bootloaders are supported
-- EFI variables can be mutated during image production and the result is exposed in `$out`
-- boot partition size when partition table is `efi` or `hybrid`
-
-### On bit-to-bit reproducibility {#sec-make-disk-image-features-reproducibility}
-
-Images are **NOT** deterministic, please do not hesitate to try to fix this, source of determinisms are (not exhaustive) :
-
-- bootloader installation have timestamps
-- SQLite Nix store database contain registration times
-- `/etc/shadow` is in a non-deterministic order
-
-A `deterministic` flag is available for best efforts determinism.
-
-## Usage {#sec-make-disk-image-usage}
-
-To produce a Nix-store only image:
-```nix
-let
-  pkgs = import <nixpkgs> {};
-  lib = pkgs.lib;
-  make-disk-image = import <nixpkgs/nixos/lib/make-disk-image.nix>;
-in
-  make-disk-image {
-    inherit pkgs lib;
-    config = {};
-    additionalPaths = [ ];
-    format = "qcow2";
-    onlyNixStore = true;
-    partitionTableType = "none";
-    installBootLoader = false;
-    touchEFIVars = false;
-    diskSize = "auto";
-    additionalSpace = "0M"; # Defaults to 512M.
-    copyChannel = false;
-  }
-```
-
-Some arguments can be left out, they are shown explicitly for the sake of the example.
-
-Building this derivation will provide a QCOW2 disk image containing only the Nix store and its registration information.
-
-To produce a NixOS installation image disk with UEFI and bootloader installed:
-```nix
-let
-  pkgs = import <nixpkgs> {};
-  lib = pkgs.lib;
-  make-disk-image = import <nixpkgs/nixos/lib/make-disk-image.nix>;
-  evalConfig = import <nixpkgs/nixos/lib/eval-config.nix>;
-in
-  make-disk-image {
-    inherit pkgs lib;
-    config = evalConfig {
-      modules = [
-        {
-          fileSystems."/" = { device = "/dev/vda"; fsType = "ext4"; autoFormat = true; };
-          boot.grub.device = "/dev/vda";
-        }

-    };
-    format = "qcow2";
-    onlyNixStore = false;
-    partitionTableType = "legacy+gpt";
-    installBootLoader = true;
-    touchEFIVars = true;
-    diskSize = "auto";

-    copyChannel = false;
-    memSize = 2048; # Qemu VM memory size in megabytes. Defaults to 1024M.

-# pkgs.portableService {#sec-pkgs-portableService}
-
-`pkgs.portableService` is a function to create _portable service images_,
-as read-only, immutable, `squashfs` archives.
-
-systemd supports a concept of [Portable Services](https://systemd.io/PORTABLE_SERVICES/).
-Portable Services are a delivery method for system services that uses two specific features of container management:
-
-* Applications are bundled. I.e. multiple services, their binaries and
-  all their dependencies are packaged in an image, and are run directly from it.
-* Stricter default security policies, i.e. sandboxing of applications.
-
-This allows using Nix to build images which can be run on many recent Linux distributions.
-
-The primary tool for interacting with Portable Services is `portablectl`,
-and they are managed by the `systemd-portabled` system service.
-
-::: {.note}
-Portable services are supported starting with systemd 239 (released on 2018-06-22).
-:::
-
-A very simple example of using `portableService` is described below:
-
-[]{#ex-pkgs-portableService}
-
-```nix
-pkgs.portableService {
-  pname = "demo";
-  version = "1.0";
-  units = [ demo-service demo-socket ];
-}
-```
-
-The above example will build an squashfs archive image in `result/$pname_$version.raw`. The image will contain the
-file system structure as required by the portable service specification, and a subset of the Nix store with all the
-dependencies of the two derivations in the `units` list.
-`units` must be a list of derivations, and their names must be prefixed with the service name (`"demo"` in this case).
-Otherwise `systemd-portabled` will ignore them.
-
-::: {.note}
-The `.raw` file extension of the image is required by the portable services specification.
-:::
-
-Some other options available are:
-- `description`, `homepage`
-
-  Are added to the `/etc/os-release` in the image and are shown by the portable services tooling.
-  Default to empty values, not added to os-release.
-- `symlinks`
-
-  A list of attribute sets {object, symlink}. Symlinks will be created  in the root filesystem of the image to
-  objects in the Nix store. Defaults to an empty list.
-- `contents`
-
-  A list of additional derivations to be included in the image Nix store, as-is. Defaults to an empty list.
-- `squashfsTools`
-
-  Defaults to `pkgs.squashfsTools`, allows you to override the package that provides `mksquashfs`.
-- `squash-compression`, `squash-block-size`
-
-  Options to `mksquashfs`. Default to `"xz -Xdict-size 100%"` and `"1M"` respectively.
-
-A typical usage of `symlinks` would be:
-```nix
-  symlinks = [
-    { object = "${pkgs.cacert}/etc/ssl"; symlink = "/etc/ssl"; }
-    { object = "${pkgs.bash}/bin/bash"; symlink = "/bin/sh"; }
-    { object = "${pkgs.php}/bin/php"; symlink = "/usr/bin/php"; }
-  ];
-```
-to create these symlinks for legacy applications that assume them existing globally.
-
-Once the image is created, and deployed on a host in `/var/lib/portables/`, you can attach the image and run the service. As root run:
-```console
-portablectl attach demo_1.0.raw
-systemctl enable --now demo.socket
-systemctl enable --now demo.service
-```
-::: {.note}
-See the [man page](https://www.freedesktop.org/software/systemd/man/portablectl.html) of `portablectl` for more info on its usage.

This happens automatically; you do not need to do modify any configuration to get this behavior.

-# darwin.builder {#sec-darwin-builder}
-
-`darwin.builder` provides a way to bootstrap a Linux builder on a macOS machine.
-
-This requires macOS version 12.4 or later.
-
-This also requires that port 22 on your machine is free (since Nix does not
-permit specifying a non-default SSH port for builders).
-
-You will also need to be a trusted user for your Nix installation.  In other
-words, your `/etc/nix/nix.conf` should have something like:
-
-```
-extra-trusted-users = <your username goes here>
-```
-
-To launch the builder, run the following flake:
-
-```ShellSession
-$ nix run nixpkgs#darwin.builder
-```
-
-That will prompt you to enter your `sudo` password:
-
-```
-+ sudo --reset-timestamp /nix/store/…-install-credentials.sh ./keys
-Password:
-```
-
-… so that it can install a private key used to `ssh` into the build server.
-After that the script will launch the virtual machine and automatically log you
-in as the `builder` user:
-
-```
-<<< Welcome to NixOS 22.11.20220901.1bd8d11 (aarch64) - ttyAMA0 >>>
-
-Run 'nixos-help' for the NixOS manual.
-
-nixos login: builder (automatic login)
-
-
-[builder@nixos:~]$
-```
-
-> Note: When you need to stop the VM, run `shutdown now` as the `builder` user.
-
-To delegate builds to the remote builder, add the following options to your
-`nix.conf` file:
-
-```
-# - Replace ${ARCH} with either aarch64 or x86_64 to match your host machine
-# - Replace ${MAX_JOBS} with the maximum number of builds (pick 4 if you're not sure)
-builders = ssh-ng://builder@localhost ${ARCH}-linux /etc/nix/builder_ed25519 ${MAX_JOBS} - - - c3NoLWVkMjU1MTkgQUFBQUMzTnphQzFsWkRJMU5URTVBQUFBSUpCV2N4Yi9CbGFxdDFhdU90RStGOFFVV3JVb3RpQzVxQkorVXVFV2RWQ2Igcm9vdEBuaXhvcwo=

-# Not strictly necessary, but this will reduce your disk utilization
-builders-use-substitutes = true

-You can build a wrapper by running your binary in `runScript`, e.g. `./bin/start.sh`. Relative paths work as expected.
-
-Additionally, the FHS builder links all relocated gsettings-schemas (the glib setup-hook moves them to `share/gsettings-schemas/${name}/glib-2.0/schemas`) to their standard FHS location. This means you don't need to wrap binaries with `wrapGAppsHook`.
+Running `nix-shell` would then drop you into a shell with these libraries and binaries available.

+## `invalidateFetcherByDrvHash` {#sec-pkgs-invalidateFetcherByDrvHash}
+
+Use the derivation hash to invalidate the output via name, for testing.
+
+Type: `(a@{ name, ... } -> Derivation) -> a -> Derivation`
+
+Normally, fixed output derivations can and should be cached by their output
+hash only, but for testing we want to re-fetch everytime the fetcher changes.
+
+Changes to the fetcher become apparent in the drvPath, which is a hash of
+how to fetch, rather than a fixed store path.
+By inserting this hash into the name, we can make sure to re-run the fetcher
+every time the fetcher changes.
+
+This relies on the assumption that Nix isn't clever enough to reuse its
+database of local store contents to optimize fetching.
+
+You might notice that the "salted" name derives from the normal invocation,
+not the final derivation. `invalidateFetcherByDrvHash` has to invoke the fetcher
+function twice: once to get a derivation hash, and again to produce the final
+fixed output derivation.
+
+Example:
+
+    tests.fetchgit = invalidateFetcherByDrvHash fetchgit {
+      name = "nix-source";
+      url = "https://github.com/NixOS/nix";

-# vmTools {#sec-vm-tools}
-
-A set of VM related utilities, that help in building some packages in more advanced scenarios.
-
-## `vmTools.createEmptyImage` {#vm-tools-createEmptyImage}
-
-A bash script fragment that produces a disk image at `destination`.
-
-### Attributes
-
-* `size`. The disk size, in MiB.
-* `fullName`. Name that will be written to `${destination}/nix-support/full-name`.
-* `destination` (optional, default `$out`). Where to write the image files.
-
-## `vmTools.runInLinuxVM` {#vm-tools-runInLinuxVM}
-
-Run a derivation in a Linux virtual machine (using Qemu/KVM).
-By default, there is no disk image; the root filesystem is a `tmpfs`, and the Nix store is shared with the host (via the [9P protocol](https://wiki.qemu.org/Documentation/9p#9p_Protocol)).
-Thus, any pure Nix derivation should run unmodified.
-
-If the build fails and Nix is run with the `-K/--keep-failed` option, a script `run-vm` will be left behind in the temporary build directory that allows you to boot into the VM and debug it interactively.
-
-### Attributes
-
-* `preVM` (optional). Shell command to be evaluated *before* the VM is started (i.e., on the host).
-* `memSize` (optional, default `512`). The memory size of the VM in MiB.
-* `diskImage` (optional). A file system image to be attached to `/dev/sda`.
-  Note that currently we expect the image to contain a filesystem, not a full disk image with a partition table etc.
-
-### Examples
-
-Build the derivation hello inside a VM:
-```nix
-{ pkgs }: with pkgs; with vmTools;
-runInLinuxVM hello
-```

-
-Example:
-
-```nix
-runCommand "example" {
-  failed = testers.testBuildFailure (runCommand "fail" {} ''
-    echo ok-ish >$out
-    echo failing though
-    exit 3
-  '');
-} ''
-  grep -F 'ok-ish' $failed/result
-  grep -F 'failing though' $failed/testBuildFailure.log
-  [[ 3 = $(cat $failed/testBuildFailure.exit) ]]
-  touch $out
-'';
-```
-
-While `testBuildFailure` is designed to keep changes to the original builder's
-environment to a minimum, some small changes are inevitable.
-
- - The file `$TMPDIR/testBuildFailure.log` is present. It should not be deleted.
- - `stdout` and `stderr` are a pipe instead of a tty. This could be improved.
- - One or two extra processes are present in the sandbox during the original
-   builder's execution.
- - The derivation and output hashes are different, but not unusual.
- - The derivation includes a dependency on `buildPackages.bash` and
-   `expect-failure.sh`, which is built to include a transitive dependency on
-   `buildPackages.coreutils` and possibly more. These are not added to `PATH`
-   or any other environment variable, so they should be hard to observe.
-
-## `testEqualContents` {#tester-equalContents}
-
-Check that two paths have the same contents.
-
-Example:
-
-```nix
-testers.testEqualContents {
-  assertion = "sed -e performs replacement";
-  expected = writeText "expected" ''
-    foo baz baz
-  '';
-  actual = runCommand "actual" {
-    # not really necessary for a package that's in stdenv
-    nativeBuildInputs = [ gnused ];
-    base = writeText "base" ''
-      foo bar baz
-    '';
-  } ''
-    sed -e 's/bar/baz/g' $base >$out
-  '';
-}
-```
-
-## `testEqualDerivation` {#tester-testEqualDerivation}
-
-Checks that two packages produce the exact same build instructions.
-
-This can be used to make sure that a certain difference of configuration,
-such as the presence of an overlay does not cause a cache miss.
-
-When the derivations are equal, the return value is an empty file.
-Otherwise, the build log explains the difference via `nix-diff`.
-
-Example:
-
-```nix
-testers.testEqualDerivation
-  "The hello package must stay the same when enabling checks."
-  hello
-  (hello.overrideAttrs(o: { doCheck = true; }))
-```
-
-## `invalidateFetcherByDrvHash` {#tester-invalidateFetcherByDrvHash}
-
-Use the derivation hash to invalidate the output via name, for testing.
-
-Type: `(a@{ name, ... } -> Derivation) -> a -> Derivation`
-
-Normally, fixed output derivations can and should be cached by their output
-hash only, but for testing we want to re-fetch everytime the fetcher changes.
-
-Changes to the fetcher become apparent in the drvPath, which is a hash of
-how to fetch, rather than a fixed store path.
-By inserting this hash into the name, we can make sure to re-run the fetcher
-every time the fetcher changes.
-
-This relies on the assumption that Nix isn't clever enough to reuse its
-database of local store contents to optimize fetching.
-
-You might notice that the "salted" name derives from the normal invocation,
-not the final derivation. `invalidateFetcherByDrvHash` has to invoke the fetcher
-function twice: once to get a derivation hash, and again to produce the final
-fixed output derivation.
-
-Example:
-
-```nix
-tests.fetchgit = testers.invalidateFetcherByDrvHash fetchgit {
-  name = "nix-source";
-  url = "https://github.com/NixOS/nix";
-  rev = "9d9dbe6ed05854e03811c361a3380e09183f4f4a";

-## `runNixOSTest` {#tester-runNixOSTest}
-
-A helper function that behaves exactly like the NixOS `runTest`, except it also assigns this Nixpkgs package set as the `pkgs` of the test and makes the `nixpkgs.*` options read-only.
-
-If your test is part of the Nixpkgs repository, or if you need a more general entrypoint, see ["Calling a test" in the NixOS manual](https://nixos.org/manual/nixos/stable/index.html#sec-calling-nixos-tests).
-
-Example:
-
-```nix
-pkgs.testers.runNixOSTest ({ lib, ... }: {
-  name = "hello";
-  nodes.machine = { pkgs, ... }: {
-    environment.systemPackages = [ pkgs.hello ];
-  };
-  testScript = ''
-    machine.succeed("hello")
-  '';
-})
-```
-
-## `nixosTest` {#tester-nixosTest}
-
-Run a NixOS VM network test using this evaluation of Nixpkgs.
-
-NOTE: This function is primarily for external use. NixOS itself uses `make-test-python.nix` directly. Packages defined in Nixpkgs [reuse NixOS tests via `nixosTests`, plural](#ssec-nixos-tests-linking).
-
-It is mostly equivalent to the function `import ./make-test-python.nix` from the
-[NixOS manual](https://nixos.org/nixos/manual/index.html#sec-nixos-tests),
-except that the current application of Nixpkgs (`pkgs`) will be used, instead of
-letting NixOS invoke Nixpkgs anew.
-
-If a test machine needs to set NixOS options under `nixpkgs`, it must set only the
-`nixpkgs.pkgs` option.
-
-### Parameter {#tester-nixosTest-parameter}
-
-A [NixOS VM test network](https://nixos.org/nixos/manual/index.html#sec-nixos-tests), or path to it. Example:
-
-```nix
-{
-  name = "my-test";
-  nodes = {
-    machine1 = { lib, pkgs, nodes, ... }: {
-      environment.systemPackages = [ pkgs.hello ];
-      services.foo.enable = true;
-    };
-    # machine2 = ...;
-  };
-  testScript = ''
-    start_all()
-    machine1.wait_for_unit("foo.service")
-    machine1.succeed("hello | foo-send")
-  '';
-}
-```
-
-### Result {#tester-nixosTest-result}
-
-A derivation that runs the VM test.
-
-Notable attributes:
-
- * `nodes`: the evaluated NixOS configurations. Useful for debugging and exploring the configuration.
-
- * `driverInteractive`: a script that launches an interactive Python session in the context of the `testScript`.

-## Individual maintainer list {#reviewing-contributions-individual-maintainer-list}
-
-When adding users to `maintainers/maintainer-list.nix`, the following
-checks should be performed:
-
--   If the user has specified a GPG key, verify that the commit is
-    signed by their key.
-
-    First, validate that the commit adding the maintainer is signed by
-    the key the maintainer listed. Check out the pull request and
-    compare its signing key with the listed key in the commit.
-
-    If the commit is not signed or it is signed by a different user, ask
-    them to either recommit using that key or to remove their key
-    information.
-
-    Given a maintainter entry like this:
-
-    ``` nix
-    {
-      example = {
-        email = "user@example.com";
-        name = "Example User";
-        keys = [{
-          fingerprint = "0000 0000 2A70 6423 0AED  3C11 F04F 7A19 AAA6 3AFE";
-        }];
-      }
-    };
-    ```
-
-    First receive their key from a keyserver:
-
-        $ gpg --recv-keys 0xF04F7A19AAA63AFE
-        gpg: key 0xF04F7A19AAA63AFE: public key "Example <user@example.com>" imported
-        gpg: Total number processed: 1
-        gpg:               imported: 1
-
-    Then check the commit is signed by that key:
-
-        $ git log --show-signature
-        commit b87862a4f7d32319b1de428adb6cdbdd3a960153
-        gpg: Signature made Wed Mar 12 13:32:24 2003 +0000

-
-            maintainers: adding example
-
-    and validate that there is a `Good signature` and the printed key
-    matches the user's submitted key.
-
-    Note: GitHub's "Verified" label does not display the user's full key
-    fingerprint, and should not be used for validating the key matches.
-
--   If the user has specified a `github` account name, ensure they have
-    also specified a `githubId` and verify the two match.
-
-    Maintainer entries that include a `github` field must also include
-    their `githubId`. People can and do change their GitHub name
-    frequently, and the ID is used as the official and stable identity
-    of the maintainer.
-
-    Given a maintainer entry like this:
-
-    ``` nix
-    {
-      example = {
-        email = "user@example.com";
-        name = "Example User";
-        github = "ghost";
-        githubId = 10137;
-      }
-    };
-    ```
-
-    First, make sure that the listed GitHub handle matches the author of
-    the commit.
-
-    Then, visit the URL `https://api.github.com/users/ghost` and
-    validate that the `id` field matches the provided `githubId`.

-
-Feel free to create a new maintainer team in `maintainers/team-list.nix`
-when a group is collectively responsible for a collection of packages.
-Use taste and personal judgement when deciding if a team is warranted.
-
-Teams are allowed to define their own rules about membership.
-
-For example, some teams will represent a business or other group which
-wants to carefully track its members. Other teams may be very open about
-who can join, and allow anybody to participate.
-
-When reviewing changes to a team, read the team's scope and the context
-around the member list for indications about the team's membership
-policy.
-
-In any case, request reviews from the existing team members. If the team
-lists no specific membership policy, feel free to merge changes to the
-team after giving the existing members a few days to respond.
