-https://github.com/NixOS/nix/blob/master/CONTRIBUTING.md
-
-Even if you've contributed to open source before, take a moment to read it,

-
-- what information to include in commit messages
-- proper attribution
-- volunteering contributions effectively
-- how to get help and our review process.

-- Thanks for your contribution!
-- To remove the stale label, just leave a new comment.
-- _How to find the right people to ping?_ → [`git blame`](https://git-scm.com/docs/git-blame) to the rescue! (or GitHub's history and blame buttons.)

-## Suggestions for PRs
-
-1. GitHub sometimes doesn't notify people who commented / reviewed a PR previously, when you (force) push commits. If you have addressed the reviews you can [officially ask for a review](https://docs.github.com/en/free-pro-team@latest/github/collaborating-with-issues-and-pull-requests/requesting-a-pull-request-review) from those who commented to you or anyone else.
-2. If it is unfinished but you plan to finish it, please mark it as a draft.
-3. If you don't expect to work on it any time soon, closing it with a short comment may encourage someone else to pick up your work.
-4. To get things rolling again, rebase the PR against the target branch and address valid comments.
-5. If you need a review to move forward, ask in [the Discourse thread for PRs that need help](https://discourse.nixos.org/t/prs-in-distress/3604).
-6. If all you need is a merge, check the git history to find and [request reviews](https://docs.github.com/en/github/collaborating-with-issues-and-pull-requests/requesting-a-pull-request-review) from people who usually merge related contributions.
-
-## Suggestions for issues
-
-1. If it is resolved (either for you personally, or in general), please consider closing it.
-2. If this might still be an issue, but you are not interested in promoting its resolution, please consider closing it while encouraging others to take over and reopen an issue if they care enough.
-3. If you still have interest in resolving it, try to ping somebody who you believe might have an interest in the topic. Consider discussing the problem in [our Discourse Forum](https://discourse.nixos.org/).
-4. As with all open source projects, your best option is to submit a Pull Request that addresses this issue. We :heart: this attitude!
-
-**Memorandum on closing issues**
-
-Don't be afraid to close an issue that holds valuable information. Closed issues stay in the system for people to search, read, cross-reference, or even reopen--nothing is lost! Closing obsolete issues is an important way to help maintainers focus their time and effort.

-# Contributing to Nix
-
-Welcome and thank you for your interest in contributing to Nix!
-We appreciate your support.
-
-Reading and following these guidelines will help us make the contribution process easy and effective for everyone involved.
-
-## Report a bug
-
-1. Check on the [GitHub issue tracker](https://github.com/NixOS/nix/issues) if your bug was already reported.
-
-2. If you were not able to find the bug or feature [open a new issue](https://github.com/NixOS/nix/issues/new/choose)
-
-3. The issue templates will guide you in specifying your issue.
-   The more complete the information you provide, the more likely it can be found by others and the more useful it is in the future.
-   Make sure reported bugs can be reproduced easily.
-
-4. Once submitted, do not expect issues to be picked up or solved right away.
-   The only way to ensure this, is to [work on the issue yourself](#making-changes-to-nix).
-
-## Report a security vulnerability
-
-Check out the [security policy](https://github.com/NixOS/nix/security/policy).
-
-## Making changes to Nix
-
-1. Search for related issues that cover what you're going to work on.
-   It could help to mention there that you will work on the issue.
-
-   We strongly recommend first-time contributors not to propose new features but rather fix tightly-scoped problems in order to build trust and a working relationship with maintainers.
-
-   Issues labeled [good first issue](https://github.com/NixOS/nix/labels/good%20first%20issue) should be relatively easy to fix and are likely to get merged quickly.
-   Pull requests addressing issues labeled [idea approved](https://github.com/NixOS/nix/labels/idea%20approved) or [RFC](https://github.com/NixOS/nix/labels/RFC) are especially welcomed by maintainers and will receive prioritised review.
-
-   If you are proficient with C++, addressing one of the [popular issues](https://github.com/NixOS/nix/issues?q=is%3Aissue+is%3Aopen+sort%3Areactions-%2B1-desc) will be highly appreciated by maintainers and Nix users all over the world.
-   For far-reaching changes, please investigate possible blockers and design implications, and coordinate with maintainers before investing too much time in writing code that may not end up getting merged.
-
-   If there is no relevant issue yet and you're not sure whether your change is likely to be accepted, [open an issue](https://github.com/NixOS/nix/issues/new/choose) yourself.
-
-2. Check for [pull requests](https://github.com/NixOS/nix/pulls) that might already cover the contribution you are about to make.
-   There are many open pull requests that might already do what you intend to work on.
-   You can use [labels](https://github.com/NixOS/nix/labels) to filter for relevant topics.
-
-3. Check the [Nix reference manual](https://nix.dev/manual/nix/development/development/building.html) for information on building Nix and running its tests.
-
-   For contributions to the command line interface, please check the [CLI guidelines](https://nix.dev/manual/nix/development/development/cli-guideline.html).
-
-4. Make your change!
-
-5. [Create a pull request](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request) for your changes.
-   * Clearly explain the problem that you're solving.
-
-     Link related issues to inform interested parties and future contributors about your change.
-     If your pull request closes one or multiple issues, mention that in the description using `Closes: #<number>`, as it will then happen automatically when your change is merged.
-   * Credit original authors when you're reusing or building on their work.
-   * Link to relevant changes in other projects, so that others can understand the full context of the change in the future when you or someone else will change or troubleshoot the code.
-     This is especially important when your change is based on work done in other repositories.
-
-     Example:
-     ```
-     This is based on the work of @user in <url>.
-     This solution took inspiration from <url>.
-
-     Co-authored-by: User Name <user@example.com>
-     ```
-
-     When cherry-picking from a different repository, use the `-x` flag, and then amend the commits to turn the hashes into URLs.
-
-   * Make sure to have [a clean history of commits on your branch by using rebase](https://www.digitalocean.com/community/tutorials/how-to-rebase-and-update-a-pull-request).
-   * [Mark the pull request as draft](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/changing-the-stage-of-a-pull-request) if you're not done with the changes.
-
-6. Do not expect your pull request to be reviewed immediately.
-   Nix maintainers follow a [structured process for reviews and design decisions](https://github.com/NixOS/nix/tree/master/maintainers#project-board-protocol), which may or may not prioritise your work.
-
-   Following this checklist will make the process smoother for everyone:
-
-   - [ ] Fixes an [idea approved](https://github.com/NixOS/nix/labels/idea%20approved) issue
-   - [ ] Tests, as appropriate:
-     - Functional tests – [`tests/functional/**.sh`](./tests/functional)
-     - Unit tests – [`src/*/tests`](./src/)
-     - Integration tests – [`tests/nixos/*`](./tests/nixos)
-   - [ ] User documentation in the [manual](./doc/manual/source)
-   - [ ] API documentation in header files
-   - [ ] Code and comments are self-explanatory
-   - [ ] Commit message explains **why** the change was made
-   - [ ] New feature or incompatible change: [add a release note](https://nix.dev/manual/nix/development/development/contributing.html#add-a-release-note)
-
-7. If you need additional feedback or help to getting pull request into shape, ask other contributors using [@mentions](https://docs.github.com/en/get-started/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax#mentioning-people-and-teams).
-
-## Making changes to the Nix manual
-
-The Nix reference manual is hosted on https://nix.dev/manual/nix.
-The underlying source files are located in [`doc/manual/source`](./doc/manual/source).
-For small changes you can [use GitHub to edit these files](https://docs.github.com/en/repositories/working-with-files/managing-files/editing-files)
-For larger changes see the [Nix reference manual](https://nix.dev/manual/nix/development/development/contributing.html).
-
-You're encouraged to add line breaks at semantic boundaries, per [sembr](https://sembr.org).
-
-## Getting help
-
-Whenever you're stuck or do not know how to proceed, you can always ask for help.
-We invite you to use our [Matrix room](https://matrix.to/#/#nix-dev:nixos.org) to ask questions.

-synopsis: "JSON format changes for store path info and derivations"
-prs: []
-issues: []
----
-
-JSON formats for store path info and derivations have been updated with new versions and structured fields.
-
-## Store Path Info JSON
-
-`nix path-info --json` now requires a `--json-format` flag to specify the output format version.
-Using `--json` without `--json-format` is deprecated and will become an error in a future release.
-For now, it defaults to version 1 with a warning, for a smoother migration.
-
-### Version 1 (`--json-format 1`)
-
-This is the legacy format, preserved for backwards compatibility:
-
-- String-based hash values (e.g., `"narHash": "sha256:FePFYIlM..."`)
-- String-based content addresses (e.g., `"ca": "fixed:r:sha256:1abc..."`)
-- Full store paths for map keys and references (e.g., `"/nix/store/abc...-foo"`)
-- Now includes `"storeDir"` field at the top level
-
-### Version 2 (`--json-format 2`)
-
-The new structured format follows the [JSON guidelines](@docroot@/development/json-guideline.md) with the following changes:
-
-- **Nested structure with top-level metadata**:
-
-  The output is now wrapped in an object with `version`, `storeDir`, and `info` fields:
-
-  ```json
-  {
-    "version": 2,
-    "storeDir": "/nix/store",
-    "info": { ... }
-  }
-  ```
-
-  The map from store bath base names to store object info is nested under the `info` field.
-
-- **Store path base names instead of full paths**:
-
-  Map keys and references use store path base names (e.g., `"abc...-foo"`) instead of full absolute store paths.
-  Combined with `storeDir`, the full path can be reconstructed.
-
-- **Structured `ca` field**:
-
-  Content address is now a structured JSON object instead of a string:
-
-  - Old: `"ca": "fixed:r:sha256:1abc..."`
-  - New: `"ca": {"method": "nar", "hash": "sha256-ungWv48Bz+pBQUDeXa4iI7ADYaOWF3qctBD/YfIAFa0="}`
-  - Still `null` values for input-addressed store objects
-
-  The `hash` field uses the [SRI](https://developer.mozilla.org/en-US/docs/Web/Security/Subresource_Integrity) format like other hashes.
-
-Nix currently only produces, and doesn't consume this format.
-
-Additionally the following field is added to both formats.
-(The `version` tracks breaking changes, and adding fields to outputted JSON is not a breaking change.)
-
-- **`version` field**:
-
-  All store path info JSON now includes `"version": <1|2>`.
-
-- **`storeDir` field**:
-
-  Top-level `"storeDir"` field contains the store directory path (e.g., `"/nix/store"`).
-
-## Derivation JSON (Version 4)
-
-The derivation JSON format has been updated from version 3 to version 4:
-
-- **Restructured inputs**:
-
-  Inputs are now nested under an `inputs` object:
-
-  - Old: `"inputSrcs": [...], "inputDrvs": {...}`
-  - New: `"inputs": {"srcs": [...], "drvs": {...}}`
-
-- **Consistent content addresses**:
-
-  Fixed content-addressed outputs now use structured JSON format.
-  This is the same format as `ca` in store path info (after the new version).
-
-Version 3 and earlier formats are *not* accepted when reading.
-
-**Affected command**: `nix derivation`, namely its `show` and `add` sub-commands.

-synopsis: Fix "download buffer is full; consider increasing the 'download-buffer-size' setting" warning
-prs: [14614]
-issues: [11728]
----
-
-The underlying issue that led to [#11728](https://github.com/NixOS/nix/issues/11728) has been resolved by utilizing
-[libcurl write pausing functionality](https://curl.se/libcurl/c/curl_easy_pause.html) to control backpressure when unpacking to slow destinations like the git-backed tarball cache. The default value of `download-buffer-size` is now 1 MiB and it's no longer recommended to increase it, since the root cause has been fixed.
-
-This is expected to improve download performance on fast connections, since previously a single slow download consumer would stall the thread and prevent any other transfers from progressing.
-
-Many thanks go out to the [Lix project](https://lix.systems/) for the [implementation](https://git.lix.systems/lix-project/lix/commit/4ae6fb5a8f0d456b8d2ba2aaca3712b4e49057fc) that served as inspiration for this change and for triaging libcurl [issues with pausing](https://github.com/curl/curl/issues/19334).

----
-
-S3 binary cache operations now happen via HTTP, leveraging `libcurl`'s native
-AWS SigV4 authentication instead of the AWS C++ SDK, providing significant
-improvements:
-
-- **Reduced memory usage**: Eliminates memory buffering issues that caused
-  segfaults with large files
-- **Fixed upload reliability**: Resolves AWS SDK chunking errors
-  (`InvalidChunkSizeError`)
-- **Lighter dependencies**: Uses lightweight `aws-crt-cpp` instead of full
-  `aws-cpp-sdk`, reducing build complexity
-
-The new implementation requires curl >= 7.75.0 and `aws-crt-cpp` for credential
-management.
-
-All existing S3 URL formats and parameters remain supported, however the store
-settings for configuring multipart uploads have changed:
-
-- **`multipart-upload`** (default: `false`): Enable multipart uploads for large
-  files. When enabled, files exceeding the multipart threshold will be uploaded
-  in multiple parts.
-
-- **`multipart-threshold`** (default: `100 MiB`): Minimum file size for using
-  multipart uploads. Files smaller than this will use regular PUT requests.
-  Only takes effect when `multipart-upload` is enabled.
-
-- **`multipart-chunk-size`** (default: `5 MiB`): Size of each part in multipart
-  uploads. Must be at least 5 MiB (AWS S3 requirement). Larger chunk sizes
-  reduce the number of requests but use more memory.
-
-- **`buffer-size`**: Has been replaced by `multipart-chunk-size` and is now an alias to it.
-
-Note that this change also means Nix now supports S3 binary cache stores even
-if built without `aws-crt-cpp`, but only for public buckets which do not
-require authentication.

-prs: [14464]
-issues: [7015]
----
-
-S3 binary cache stores now support configuring the storage class for uploaded objects via the `storage-class` parameter. This allows users to optimize costs by selecting appropriate storage tiers based on access patterns.
-
-Example usage:
-
-```bash
-# Use Glacier storage for long-term archival
-nix copy --to 's3://my-bucket?storage-class=GLACIER' /nix/store/...
-
-# Use Intelligent Tiering for automatic cost optimization
-nix copy --to 's3://my-bucket?storage-class=INTELLIGENT_TIERING' /nix/store/...
-```
-
-The storage class applies to both regular uploads and multipart uploads. When not specified, objects use the bucket's default storage class.
-
-See the [S3 storage classes documentation](https://docs.aws.amazon.com/AmazonS3/latest/userguide/storage-class-intro.html) for available storage classes and their characteristics.

-# Verifying Build Reproducibility
-
-You can use Nix's `diff-hook` setting to compare build results. Note
-that this hook is only executed if the results differ; it is not used
-for determining if the results are the same.
-
-For purposes of demonstration, we'll use the following Nix file,
-`deterministic.nix` for testing:
-
-```nix
-let
-  inherit (import <nixpkgs> {}) runCommand;
-in {
-  stable = runCommand "stable" {} ''
-    touch $out
-  '';
-
-  unstable = runCommand "unstable" {} ''
-    echo $RANDOM > $out
-  '';
-}
-```
-
-Additionally, `nix.conf` contains:
-
-    diff-hook = /etc/nix/my-diff-hook
-    run-diff-hook = true
-
-where `/etc/nix/my-diff-hook` is an executable file containing:
-
-```bash
-#!/bin/sh
-exec >&2
-echo "For derivation $3:"
-/run/current-system/sw/bin/diff -r "$1" "$2"
-```
-
-The diff hook is executed by the same user and group who ran the build.
-However, the diff hook does not have write access to the store path just
-built.
-
-# Spot-Checking Build Determinism
-
-Verify a path which already exists in the Nix store by passing `--check`
-to the build command.
-
-If the build passes and is deterministic, Nix will exit with a status
-code of 0:
-
-```console
-$ nix-build ./deterministic.nix --attr stable
-this derivation will be built:
-  /nix/store/z98fasz2jqy9gs0xbvdj939p27jwda38-stable.drv
-building '/nix/store/z98fasz2jqy9gs0xbvdj939p27jwda38-stable.drv'...
-/nix/store/yyxlzw3vqaas7wfp04g0b1xg51f2czgq-stable
-
-$ nix-build ./deterministic.nix --attr stable --check
-checking outputs of '/nix/store/z98fasz2jqy9gs0xbvdj939p27jwda38-stable.drv'...
-/nix/store/yyxlzw3vqaas7wfp04g0b1xg51f2czgq-stable
-```
-
-If the build is not deterministic, Nix will exit with a status code of
-1:
-
-```console
-$ nix-build ./deterministic.nix --attr unstable
-this derivation will be built:
-  /nix/store/cgl13lbj1w368r5z8gywipl1ifli7dhk-unstable.drv
-building '/nix/store/cgl13lbj1w368r5z8gywipl1ifli7dhk-unstable.drv'...
-/nix/store/krpqk0l9ib0ibi1d2w52z293zw455cap-unstable
-
-$ nix-build ./deterministic.nix --attr unstable --check
-checking outputs of '/nix/store/cgl13lbj1w368r5z8gywipl1ifli7dhk-unstable.drv'...
-error: derivation '/nix/store/cgl13lbj1w368r5z8gywipl1ifli7dhk-unstable.drv' may
-not be deterministic: output '/nix/store/krpqk0l9ib0ibi1d2w52z293zw455cap-unstable' differs
-```
-
-In the Nix daemon's log, we will now see:
-
-```
-For derivation /nix/store/cgl13lbj1w368r5z8gywipl1ifli7dhk-unstable.drv:
-1c1
-< 8108
----
-> 30204
-```
-
-Using `--check` with `--keep-failed` will cause Nix to keep the second
-build's output in a special, `.check` path:
-
-```console
-$ nix-build ./deterministic.nix --attr unstable --check --keep-failed
-checking outputs of '/nix/store/cgl13lbj1w368r5z8gywipl1ifli7dhk-unstable.drv'...
-note: keeping build directory '/tmp/nix-build-unstable.drv-0'
-error: derivation '/nix/store/cgl13lbj1w368r5z8gywipl1ifli7dhk-unstable.drv' may
-not be deterministic: output '/nix/store/krpqk0l9ib0ibi1d2w52z293zw455cap-unstable' differs
-from '/nix/store/krpqk0l9ib0ibi1d2w52z293zw455cap-unstable.check'
-```
-
-In particular, notice the
-`/nix/store/krpqk0l9ib0ibi1d2w52z293zw455cap-unstable.check` output. Nix
-has copied the build results to that directory where you can examine it.
-
-> []{#check-dirs-are-unregistered} **Note**
-> 
-> Check paths are not protected against garbage collection, and this
-> path will be deleted on the next garbage collection.
-> 
-> The path is guaranteed to be alive for the duration of
-> the `diff-hook`'s execution, but may be deleted any time after.
-> 
-> If the comparison is performed as part of automated tooling, please
-> use the diff-hook or author your tooling to handle the case where the
-> build was not deterministic and also a check path does not exist.
-
-`--check` is only usable if the derivation has been built on the system
-already. If the derivation has not been built Nix will fail with the
-error:
-
-    error: some outputs of '/nix/store/hzi1h60z2qf0nb85iwnpvrai3j2w7rr6-unstable.drv' 
-    are not valid, so checking is not possible
-
-Run the build without `--check`, and then try with `--check` again.

-# Remote Builds
-
-A local Nix installation can forward Nix builds to other machines,
-this allows multiple builds to be performed in parallel.
-
-Remote builds also allow Nix to perform multi-platform builds in a
-semi-transparent way. For example, if you perform a build for a
-`x86_64-darwin` on an `i686-linux` machine, Nix can automatically
-forward the build to a `x86_64-darwin` machine, if one is available.
-
-## Requirements
-
-For a local machine to forward a build to a remote machine, the remote machine must:
-
-- Have Nix installed
-- Be running an SSH server, e.g. `sshd`
-- Be accessible via SSH from the local machine over the network
-- Have the local machine's public SSH key in `/etc/ssh/authorized_keys.d/<username>`
-- Have the username of the SSH user in the `trusted-users` setting in `nix.conf`
-
-## Testing
-
-To test connecting to a remote [Nix instance] (in this case `mac`), run:
-
-```console
-nix store info --store ssh://username@mac
-```
-
-To specify an SSH identity file as part of the remote store URI add a
-query parameter, e.g.
-
-```console
-nix store info --store ssh://username@mac?ssh-key=/home/alice/my-key
-```
-
-Since builds should be non-interactive, the key should not have a
-passphrase. Alternatively, you can load identities ahead of time into
-`ssh-agent` or `gpg-agent`.
-
-In a multi-user installation (default), builds are executed by the Nix
-Daemon. The Nix Daemon cannot prompt for a passphrase via the terminal
-or `ssh-agent`, so the SSH key must not have a passphrase.
-
-In addition, the Nix Daemon's user (typically root) needs to have SSH
-access to the remote builder.
-
-Access can be verified by running `sudo su`, and then validating SSH
-access, e.g. by running `ssh mac`. SSH identity files for root users
-are usually stored in `/root/.ssh/` (Linux) or `/var/root/.ssh` (MacOS).
-
-If you get the error
-
-```console
-bash: nix: command not found
-error: cannot connect to 'mac'
-```
-
-then you need to ensure that the `PATH` of non-interactive login shells
-contains Nix.
-
-The [list of remote build machines](@docroot@/command-ref/conf-file.md#conf-builders) can be specified on the command line or in the Nix configuration file.
-For example, the following command allows you to build a derivation for `x86_64-darwin` on a Linux machine:
-
-```console
-uname
-```
-
-```console
-Linux
-```
-
-```console
-nix build --impure \
- --expr '(with import <nixpkgs> { system = "x86_64-darwin"; }; runCommand "foo" {} "uname > $out")' \
- --builders 'ssh://mac x86_64-darwin'
-```
-
-```console
-[1/0/1 built, 0.0 MiB DL] building foo on ssh://mac
-```
-
-```console
-cat ./result
-```
-
-```console
-Darwin
-```
-
-It is possible to specify multiple build machines separated by a semicolon or a newline, e.g.
-
-```console
-  --builders 'ssh://mac x86_64-darwin ; ssh://beastie x86_64-freebsd'
-```
-
-Remote build machines can also be configured in [`nix.conf`](@docroot@/command-ref/conf-file.md), e.g.
-
-    builders = ssh://mac x86_64-darwin ; ssh://beastie x86_64-freebsd
-
-After making changes to `nix.conf`, restart the Nix daemon for changes to take effect.
-
-Finally, remote build machines can be configured in a separate configuration
-file included in `builders` via the syntax `@/path/to/file`. For example,
-
-    builders = @/etc/nix/machines
-
-causes the list of machines in `/etc/nix/machines` to be included.
-(This is the default.)

-# Using the `post-build-hook`
-
-# Implementation Caveats
-
-Here we use the post-build hook to upload to a binary cache. This is a
-simple and working example, but it is not suitable for all use cases.
-
-The post build hook program runs after each executed build, and blocks
-the build loop. The build loop exits if the hook program fails.
-
-Concretely, this implementation will make Nix slow or unusable when the
-internet is slow or unreliable.
-
-A more advanced implementation might pass the store paths to a
-user-supplied daemon or queue for processing the store paths outside of
-the build loop.
-
-# Prerequisites
-
-This tutorial assumes you have configured an [S3-compatible binary cache](@docroot@/command-ref/new-cli/nix3-help-stores.md#s3-binary-cache-store) as a [substituter](../command-ref/conf-file.md#conf-substituters),
-and that the `root` user's default AWS profile can upload to the bucket.
-
-# Set up a Signing Key
-
-Use `nix-store --generate-binary-cache-key` to create our public and
-private signing keys. We will sign paths with the private key, and
-distribute the public key for verifying the authenticity of the paths.
-
-```console
-# nix-store --generate-binary-cache-key example-nix-cache-1 /etc/nix/key.private /etc/nix/key.public
-# cat /etc/nix/key.public
-example-nix-cache-1:1/cKDz3QCCOmwcztD2eV6Coggp6rqc9DGjWv7C0G+rM=
-```
-
-Then update [`nix.conf`](../command-ref/conf-file.md) on any machine that will access the cache.
-Add the cache URL to [`substituters`](../command-ref/conf-file.md#conf-substituters) and the public key to [`trusted-public-keys`](../command-ref/conf-file.md#conf-trusted-public-keys):
-
-    substituters = https://cache.nixos.org/ s3://example-nix-cache
-    trusted-public-keys = cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY= example-nix-cache-1:1/cKDz3QCCOmwcztD2eV6Coggp6rqc9DGjWv7C0G+rM=
-
-Machines that build for the cache must sign derivations using the private key.
-On those machines, add the path to the key file to the [`secret-key-files`](../command-ref/conf-file.md#conf-secret-key-files) field in their [`nix.conf`](../command-ref/conf-file.md):
-
-    secret-key-files = /etc/nix/key.private
-
-We will restart the Nix daemon in a later step.
-
-# Implementing the build hook
-
-Write the following script to `/etc/nix/upload-to-cache.sh`:
-
-```bash
-#!/bin/sh
-
-set -eu
-set -f # disable globbing
-export IFS=' '
-
-echo "Uploading paths" $OUT_PATHS
-exec nix copy --to "s3://example-nix-cache" $OUT_PATHS
-```
-
-> **Note**
->
-> The `$OUT_PATHS` variable is a space-separated list of Nix store
-> paths. In this case, we expect and want the shell to perform word
-> splitting to make each output path its own argument to `nix
-> store sign`. Nix guarantees the paths will not contain any spaces,
-> however a store path might contain glob characters. The `set -f`
-> disables globbing in the shell.
-> If you want to upload the `.drv` file too, the `$DRV_PATH` variable
-> is also defined for the script and works just like `$OUT_PATHS`.
-
-Then make sure the hook program is executable by the `root` user:
-
-```console
-# chmod +x /etc/nix/upload-to-cache.sh
-```
-
-# Updating Nix Configuration
-
-Edit `/etc/nix/nix.conf` to run our hook, by adding the following
-configuration snippet at the end:
-
-    post-build-hook = /etc/nix/upload-to-cache.sh
-
-Then, restart the `nix-daemon`.
-
-# Testing
-
-Build any derivation, for example:
-
-```console
-$ nix-build --expr '(import <nixpkgs> {}).writeText "example" (builtins.toString builtins.currentTime)'
-this derivation will be built:
-  /nix/store/s4pnfbkalzy5qz57qs6yybna8wylkig6-example.drv
-building '/nix/store/s4pnfbkalzy5qz57qs6yybna8wylkig6-example.drv'...
-running post-build-hook '/home/grahamc/projects/github.com/NixOS/nix/post-hook.sh'...
-post-build-hook: Signing paths /nix/store/ibcyipq5gf91838ldx40mjsp0b8w9n18-example
-post-build-hook: Uploading paths /nix/store/ibcyipq5gf91838ldx40mjsp0b8w9n18-example
-/nix/store/ibcyipq5gf91838ldx40mjsp0b8w9n18-example
-```
-
-Then delete the path from the store, and try substituting it from the
-binary cache:
-
-```console
-$ rm ./result
-$ nix-store --delete /nix/store/ibcyipq5gf91838ldx40mjsp0b8w9n18-example
-```
-
-Now, copy the path back from the cache:
-
-```console
-$ nix-store --realise /nix/store/ibcyipq5gf91838ldx40mjsp0b8w9n18-example
-copying path '/nix/store/m8bmqwrch6l3h8s0k3d673xpmipcdpsa-example from 's3://example-nix-cache'...
-warning: you did not specify '--add-root'; the result might be removed by the garbage collector
-/nix/store/m8bmqwrch6l3h8s0k3d673xpmipcdpsa-example
-```
-
-# Conclusion
-
-We now have a Nix installation configured to automatically sign and
-upload every local build to a remote binary cache.
-
-Before deploying this to production, be sure to consider the
-[implementation caveats](#implementation-caveats).

-
-At the top is the [command line interface](../command-ref/index.md) that drives the underlying layers.
-
-The [Nix language](../language/index.md) evaluator transforms Nix expressions into self-contained *build plans*, which are used to derive *build results* from referenced *build inputs*.
-
-The command line interface and Nix expressions are what users deal with most.
-
-> **Note**
->
-> The Nix language itself does not have a notion of *packages* or *configurations*.
-> As far as we are concerned here, the inputs and results of a build plan are just data.
-
-Underlying the command line interface and the Nix language evaluator is the [Nix store](../store/index.md), a mechanism to keep track of build plans, data, and references between them.
-It can also execute build plans to produce new data, which are made available to the operating system as files.
-
-A build plan itself is a series of *build tasks*, together with their build inputs.
-
-> **Important**
-> A build task in Nix is called [store derivation](@docroot@/glossary.md#gloss-store-derivation).
-
-Each build task has a special build input executed as *build instructions* in order to perform the build.
-The result of a build task can be input to another build task.
-
-The following [data flow diagram] shows a build plan for illustration.
-Build inputs used as instructions to a build task are marked accordingly:

-# Name
-
-`nix.conf` - Nix configuration file
-
-# Description
-
-Nix supports a variety of configuration settings, which are read from configuration files or taken as command line flags.
-
-## Configuration file
-
-By default Nix reads settings from the following places, in that order:
-
-1. The system-wide configuration file `sysconfdir/nix/nix.conf` (i.e. `/etc/nix/nix.conf` on most systems), or `$NIX_CONF_DIR/nix.conf` if [`NIX_CONF_DIR`](./env-common.md#env-NIX_CONF_DIR) is set.
-
-   Values loaded in this file are not forwarded to the Nix daemon.
-   The client assumes that the daemon has already loaded them.
-
-1. If [`NIX_USER_CONF_FILES`](./env-common.md#env-NIX_USER_CONF_FILES) is set, then each path separated by `:` will be loaded in reverse order.
-
-   Otherwise it will look for `nix/nix.conf` files in `XDG_CONFIG_DIRS` and [`XDG_CONFIG_HOME`](./env-common.md#env-XDG_CONFIG_HOME).
-   If unset, `XDG_CONFIG_DIRS` defaults to `/etc/xdg`, and `XDG_CONFIG_HOME` defaults to `$HOME/.config` as per [XDG Base Directory Specification](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html).
-
-1. If [`NIX_CONFIG`](./env-common.md#env-NIX_CONFIG) is set, its contents are treated as the contents of a configuration file.
-
-### File format
-
-Configuration files consist of `name = value` pairs, one per line.
-Comments start with a `#` character.
-
-Example:
-
-```
-keep-outputs = true       # Nice for developers
-keep-derivations = true   # Idem
-```
-
-Other files can be included with a line like `include <path>`, where `<path>` is interpreted relative to the current configuration file.
-A missing file is an error unless `!include` is used instead.
-
-A configuration setting usually overrides any previous value.
-However, for settings that take a list of items, you can prefix the name of the setting by `extra-` to *append* to the previous value.
-
-For instance,
-
-```
-substituters = a b
-extra-substituters = c d
-```
-
-defines the `substituters` setting to be `a b c d`.
-
-Unknown option names are not an error, and are simply ignored with a warning.
-
-## Command line flags
-
-Configuration options can be set on the command line, overriding the values set in the [configuration file](#configuration-file):
-
-- Every configuration setting has corresponding command line flag (e.g. `--max-jobs 16`).
-  Boolean settings do not need an argument, and can be explicitly disabled with the `no-` prefix (e.g. `--keep-failed` and `--no-keep-failed`).
-
-  Unknown option names are invalid flags (unless there is already a flag with that name), and are rejected with an error.
-
-- The flag `--option <name> <value>` is interpreted exactly like a `<name> = <value>` in a setting file.
-
-  Unknown option names are ignored with a warning.
-
-The `extra-` prefix is supported for settings that take a list of items (e.g. `--extra-trusted users alice` or `--option extra-trusted-users alice`).
-
-## Integer settings
-
-Settings that have an integer type support the suffixes `K`, `M`, `G`
-and `T`. These cause the specified value to be multiplied by 2^10,
-2^20, 2^30 and 2^40, respectively. For instance, `--min-free 1M` is
-equivalent to `--min-free 1048576`.

-# Common Environment Variables
-
-Most Nix commands interpret the following environment variables:
-
-- <span id="env-IN_NIX_SHELL">[`IN_NIX_SHELL`](#env-IN_NIX_SHELL)</span>
-
-  Indicator that tells if the current environment was set up by
-  `nix-shell`. It can have the values `pure` or `impure`.
-
-- <span id="env-NIX_PATH">[`NIX_PATH`](#env-NIX_PATH)</span>
-
-  A colon-separated list of search path entries used to resolve [lookup paths](@docroot@/language/constructs/lookup-path.md).
-
-  This environment variable overrides the value of the [`nix-path` configuration setting](@docroot@/command-ref/conf-file.md#conf-nix-path).
-
-  It can be extended using the [`-I` option](@docroot@/command-ref/opt-common.md#opt-I).
-
-  > **Example**
-  >
-  > ```bash
-  > $ export NIX_PATH=`/home/eelco/Dev:nixos-config=/etc/nixos
-  > ```
-
-  If `NIX_PATH` is set to an empty string, resolving search paths will always fail.
-
-  > **Example**
-  >
-  > ```bash
-  > $ NIX_PATH= nix-instantiate --eval '<nixpkgs>'
-  > error: file 'nixpkgs' was not found in the Nix search path (add it using $NIX_PATH or -I)
-  > ```
-
-- <span id="env-NIX_IGNORE_SYMLINK_STORE">[`NIX_IGNORE_SYMLINK_STORE`](#env-NIX_IGNORE_SYMLINK_STORE)</span>
-
-  Normally, the Nix store directory (typically `/nix/store`) is not
-  allowed to contain any symlink components. This is to prevent
-  “impure” builds. Builders sometimes “canonicalise” paths by
-  resolving all symlink components. Thus, builds on different machines
-  (with `/nix/store` resolving to different locations) could yield
-  different results. This is generally not a problem, except when
-  builds are deployed to machines where `/nix/store` resolves
-  differently. If you are sure that you’re not going to do that, you
-  can set `NIX_IGNORE_SYMLINK_STORE` to `1`.
-
-  Note that if you’re symlinking the Nix store so that you can put it
-  on another file system than the root file system, on Linux you’re
-  better off using `bind` mount points, e.g.,
-
-  ```console
-  $ mkdir /nix
-  $ mount -o bind /mnt/otherdisk/nix /nix
-  ```
-
-  Consult the mount 8 manual page for details.
-
-- <span id="env-NIX_STORE_DIR">[`NIX_STORE_DIR`](#env-NIX_STORE_DIR)</span>

-  Overrides the location of the Nix store (default `prefix/store`).
-
-- <span id="env-NIX_DATA_DIR">[`NIX_DATA_DIR`](#env-NIX_DATA_DIR)</span>
-
-  Overrides the location of the Nix static data directory (default
-  `prefix/share`).
-
-- <span id="env-NIX_LOG_DIR">[`NIX_LOG_DIR`](#env-NIX_LOG_DIR)</span>

-  `prefix/var/log/nix`).
-
-- <span id="env-NIX_STATE_DIR">[`NIX_STATE_DIR`](#env-NIX_STATE_DIR)</span>
-
-  Overrides the location of the Nix state directory (default
-  `prefix/var/nix`).
-
-- <span id="env-NIX_CONF_DIR">[`NIX_CONF_DIR`](#env-NIX_CONF_DIR)</span>
-
-  Overrides the location of the system Nix configuration directory
-  (default `sysconfdir/nix`, i.e. `/etc/nix` on most systems).
-
-- <span id="env-NIX_CONFIG">[`NIX_CONFIG`](#env-NIX_CONFIG)</span>
-
-  Applies settings from Nix configuration from the environment.
-  The content is treated as if it was read from a Nix configuration file.
-  Settings are separated by the newline character.
-
-- <span id="env-NIX_USER_CONF_FILES">[`NIX_USER_CONF_FILES`](#env-NIX_USER_CONF_FILES)</span>
-
-  Overrides the location of the Nix user configuration files to load from.
-
-  The default are the locations according to the [XDG Base Directory Specification].
-  See the [XDG Base Directories](#xdg-base-directories) sub-section for details.
-
-  The variable is treated as a list separated by the `:` token.
-
-- <span id="env-TMPDIR">[`TMPDIR`](#env-TMPDIR)</span>
-
-  Use the specified directory to store temporary files. In particular,
-  this includes temporary build directories; these can take up
-  substantial amounts of disk space. The default is `/tmp`.
-
-- <span id="env-NIX_REMOTE">[`NIX_REMOTE`](#env-NIX_REMOTE)</span>
-
-  This variable should be set to `daemon` if you want to use the Nix
-  daemon to execute Nix operations. This is necessary in [multi-user
-  Nix installations](@docroot@/installation/multi-user.md). If the Nix
-  daemon's Unix socket is at some non-standard path, this variable
-  should be set to `unix://path/to/socket`. Otherwise, it should be
-  left unset.
-
-- <span id="env-NIX_SHOW_STATS">[`NIX_SHOW_STATS`](#env-NIX_SHOW_STATS)</span>
-
-  If set to `1`, Nix will print some evaluation statistics, such as
-  the number of values allocated.
-
-- <span id="env-NIX_COUNT_CALLS">[`NIX_COUNT_CALLS`](#env-NIX_COUNT_CALLS)</span>
-
-  If set to `1`, Nix will print how often functions were called during
-  Nix expression evaluation. This is useful for profiling your Nix
-  expressions.
-
-- <span id="env-GC_INITIAL_HEAP_SIZE">[`GC_INITIAL_HEAP_SIZE`](#env-GC_INITIAL_HEAP_SIZE)</span>
-
-  If Nix has been configured to use the Boehm garbage collector, this
-  variable sets the initial size of the heap in bytes. It defaults to
-  384 MiB. Setting it to a low value reduces memory consumption, but
-  will increase runtime due to the overhead of garbage collection.
-
-## XDG Base Directories
-
-Nix follows the [XDG Base Directory Specification].
-
-For backwards compatibility, Nix commands will follow the standard only when [`use-xdg-base-directories`] is enabled.
-[New Nix commands](@docroot@/command-ref/new-cli/nix.md) (experimental) conform to the standard by default.
-
-The following environment variables are used to determine locations of various state and configuration files:
-
-- [`XDG_CONFIG_HOME`]{#env-XDG_CONFIG_HOME} (default `~/.config`)
-- [`XDG_STATE_HOME`]{#env-XDG_STATE_HOME} (default `~/.local/state`)
-- [`XDG_CACHE_HOME`]{#env-XDG_CACHE_HOME} (default `~/.cache`)
-
-[XDG Base Directory Specification]: https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html
-[`use-xdg-base-directories`]: @docroot@/command-ref/conf-file.md#conf-use-xdg-base-directories
-
-In addition, setting the following environment variables overrides the XDG base directories:
-
-- [`NIX_CONFIG_HOME`]{#env-NIX_CONFIG_HOME} (default `$XDG_CONFIG_HOME/nix`)
-- [`NIX_STATE_HOME`]{#env-NIX_STATE_HOME} (default `$XDG_STATE_HOME/nix`)
-- [`NIX_CACHE_HOME`]{#env-NIX_CACHE_HOME} (default `$XDG_CACHE_HOME/nix`)
-
-When [`use-xdg-base-directories`] is enabled, the configuration directory is:
-
-1. `$NIX_CONFIG_HOME`, if it is defined
-2. Otherwise, `$XDG_CONFIG_HOME/nix`, if `XDG_CONFIG_HOME` is defined
-3. Otherwise, `~/.config/nix`.
-
-Likewise for the state and cache directories.

-- `$XDG_STATE_HOME/nix/defexpr` if [`use-xdg-base-directories`] is set to `true`.
-
-It is loaded as follows:
-
-- If the default expression is a file, it is loaded as a Nix expression.
-- If the default expression is a directory containing a `default.nix` file, that `default.nix` file is loaded as a Nix expression.
-- If the default expression is a directory without a `default.nix` file, then its contents (both files and subdirectories) are loaded as Nix expressions.
-  The expressions are combined into a single attribute set, each expression under an attribute with the same name as the original file or subdirectory.
-  Subdirectories without a `default.nix` file are traversed recursively in search of more Nix expressions, but the names of these intermediate directories are not added to the attribute paths of the default Nix expression.
-
-Then, the resulting expression is interpreted like this:
-
-- If the expression is an attribute set, it is used as the default Nix expression.
-- If the expression is a function, an empty set is passed as argument and the return value is used as the default Nix expression.

-### Filesystem layout

-Profiles are versioned as follows. When using a profile named *path*, *path* is a symlink to *path*`-`*N*`-link`, where *N* is the version of the profile.
-In turn, *path*`-`*N*`-link` is a symlink to a path in the Nix store.

-# Name
-
-`nix-build` - build a Nix expression
-
-# Synopsis
-
-`nix-build` [*paths…*]
-  [`--arg` *name* *value*]
-  [`--argstr` *name* *value*]
-  [{`--attr` | `-A`} *attrPath*]
-  [`--no-out-link`]
-  [`--dry-run`]
-  [{`--out-link` | `-o`} *outlink*]
-
-# Disambiguation
-
-This man page describes the command `nix-build`, which is distinct from `nix
-build`. For documentation on the latter, run `nix build --help` or see `man
-nix3-build`.
-
-# Description
-
-The `nix-build` command builds the derivations described by the Nix
-expressions in *paths*. If the build succeeds, it places a symlink to
-the result in the current directory. The symlink is called `result`. If
-there are multiple Nix expressions, or the Nix expressions evaluate to
-multiple derivations, multiple sequentially numbered symlinks are
-created (`result`, `result-2`, and so on).
-
-If no *paths* are specified, then `nix-build` will use `default.nix` in
-the current directory, if it exists.
-
-If an element of *paths* starts with `http://` or `https://`, it is
-interpreted as the URL of a tarball that will be downloaded and unpacked
-to a temporary location. The tarball must include a single top-level
-directory containing at least a file named `default.nix`.
-
-`nix-build` is essentially a wrapper around
-[`nix-instantiate`](./nix-instantiate.md) (to translate a high-level Nix
-expression to a low-level [store derivation]) and [`nix-store
---realise`](@docroot@/command-ref/nix-store/realise.md) (to build the store
-derivation).
-
-[store derivation]: @docroot@/glossary.md#gloss-store-derivation
-
-> **Warning**
->
-> The result of the build is automatically registered as a root of the
-> Nix garbage collector. This root disappears automatically when the
-> `result` symlink is deleted or renamed. So don’t rename the symlink.
-
-# Options
-
-All options not listed here are passed to
-[`nix-store --realise`](./nix-store/realise.md),
-except for `--arg` and `--attr` / `-A` which are passed to [`nix-instantiate`](./nix-instantiate.md).
-
-- <span id="opt-no-out-link">[`--no-out-link`](#opt-no-out-link)<span>
-
-  Do not create a symlink to the output path. Note that as a result
-  the output does not become a root of the garbage collector, and so
-  might be deleted by `nix-store --gc`.
-
-- <span id="opt-dry-run">[`--dry-run`](#opt-dry-run)</span>
-
-  Show what store paths would be built or downloaded.
-
-- <span id="opt-out-link">[`--out-link`](#opt-out-link)</span> / `-o` *outlink*
-
-  Change the name of the symlink to the output path created from
-  `result` to *outlink*.

-```console
-$ nix-build '<nixpkgs>' --attr firefox
-store derivation is /nix/store/qybprl8sz2lc...-firefox-1.5.0.7.drv
-/nix/store/d18hyl92g30l...-firefox-1.5.0.7
-

-lrwxrwxrwx  ...  result -> /nix/store/d18hyl92g30l...-firefox-1.5.0.7
-
-$ ls ./result/bin/
-firefox  firefox-config
-```
-
-If a derivation has multiple outputs, `nix-build` will build the default
-(first) output. You can also build all outputs:
-
-```console
-$ nix-build '<nixpkgs>' --attr openssl.all
-```
-
-This will create a symlink for each output named `result-outputname`.
-The suffix is omitted if the output name is `out`. So if `openssl` has
-outputs `out`, `bin` and `man`, `nix-build` will create symlinks
-`result`, `result-bin` and `result-man`. It’s also possible to build a
-specific output:
-
-```console
-$ nix-build '<nixpkgs>' --attr openssl.man
-```
-
-This will create a symlink `result-man`.
-
-Build a Nix expression given on the command line:
-
-```console
-$ nix-build --expr 'with import <nixpkgs> { }; runCommand "foo" { } "echo bar > $out"'
-$ cat ./result
-bar
-```
-
-Build the GNU Hello package from the latest revision of the master
-branch of Nixpkgs:
-
-```console
-$ nix-build https://github.com/NixOS/nixpkgs/archive/master.tar.gz --attr hello
-```

-# Synopsis
-
-`nix-channel` {`--add` url [*name*] | `--remove` *name* | `--list` | `--update` [*names…*] | `--list-generations` | `--rollback` [*generation*] }
-
-# Description
-
-Channels are a mechanism for referencing remote Nix expressions and conveniently retrieving their latest version.
-
-The moving parts of channels are:
-- The official channels listed at <https://channels.nixos.org>
-- The user-specific list of [subscribed channels](#subscribed-channels)
-- The [downloaded channel contents](#channels)
-- The [Nix expression search path](@docroot@/command-ref/conf-file.md#conf-nix-path), set with the [`-I` option](#opt-I) or the [`NIX_PATH` environment variable](#env-NIX_PATH)
-
-> **Note**
->
-> The state of a subscribed channel is external to the Nix expressions relying on it.
-> This may limit reproducibility.
->
-> Dependencies on other Nix expressions can be declared explicitly with:
-> - [`fetchurl`](@docroot@/language/builtins.md#builtins-fetchurl), [`fetchTarball`](@docroot@/language/builtins.md#builtins-fetchTarball), or [`fetchGit`](@docroot@/language/builtins.md#builtins-fetchGit) in Nix expressions
-> - the [`-I` option](@docroot@/command-ref/opt-common.md#opt-I) in command line invocations
-
-This command has the following operations:
-
-- `--add` *url* \[*name*\]
-
-  Add a channel *name* located at *url* to the list of subscribed channels.
-  If *name* is omitted, default to the last component of *url*, with the suffixes `-stable` or `-unstable` removed.
-
-  > **Note**
-  >
-  > `--add` does not automatically perform an update.
-  > Use `--update` explicitly.
-
-  A channel URL must point to a directory containing a file `nixexprs.tar.gz`.
-  At the top level, that tarball must contain a single directory with a `default.nix` file that serves as the channel’s entry point.
-
-- `--remove` *name*
-
-  Remove the channel *name* from the list of subscribed channels.
-
-- `--list`
-
-  Print the names and URLs of all subscribed channels on standard output.
-
-- `--update` \[*names*…\]
-
-  Download the Nix expressions of subscribed channels and create a new generation.
-  Update all channels if none is specified, and only those included in *names* otherwise.
-
-  > **Note**
-  >
-  > Downloaded channel contents are cached.
-  > Use `--tarball-ttl` or the [`tarball-ttl` configuration option](@docroot@/command-ref/conf-file.md#conf-tarball-ttl) to change the validity period of cached downloads.
-
-- `--list-generations`
-
-  Prints a list of all the current existing generations for the
-  channel profile.
-
-  Works the same way as
-  ```
-  nix-env --profile /nix/var/nix/profiles/per-user/$USER/channels --list-generations
-  ```
-
-- `--rollback` \[*generation*\]
-
-  Revert channels to the state before the last call to `nix-channel --update`.
-  Optionally, you can specify a specific channel *generation* number to restore.
-
-{{#include ./opt-common.md}}
-
-{{#include ./env-common.md}}
-
-# Files
-
-`nix-channel` operates on the following files.
-
-{{#include ./files/channels.md}}
-
-# Examples
-
-Subscribe to the Nixpkgs channel and run `hello` from the GNU Hello package:
-
-```console
-$ nix-channel --add https://channels.nixos.org/nixpkgs-unstable
-$ nix-channel --list
-nixpkgs https://channels.nixos.org/nixpkgs
-$ nix-channel --update
-$ nix-shell -p hello --run hello
-hello
-```
-
-Revert channel updates using `--rollback`:
-
-```console
-$ nix-instantiate --eval '<nixpkgs>' --attr lib.version
-"22.11pre296212.530a53dcbc9"
-
-$ nix-channel --rollback
-switching from generation 483 to 482
-
-$ nix-instantiate --eval '<nixpkgs>' --attr lib.version
-"22.11pre281526.d0419badfad"

-# Synopsis
-
-`nix-collect-garbage` [`--delete-old`] [`-d`] [`--delete-older-than` *period*] [`--max-freed` *bytes*] [`--dry-run`]
-
-# Description
-
-The command `nix-collect-garbage` is mostly an alias of [`nix-store --gc`](@docroot@/command-ref/nix-store/gc.md).
-That is, it deletes all unreachable [store objects] in the Nix store to clean up your system.
-
-However, it provides two additional options,
-[`--delete-old`](#opt-delete-old) and [`--delete-older-than`](#opt-delete-older-than),
-which also delete old [profiles], allowing potentially more [store objects] to be deleted because profiles are also garbage collection roots.
-These options are the equivalent of running
-[`nix-env --delete-generations`](@docroot@/command-ref/nix-env/delete-generations.md)
-with various augments on multiple profiles,
-prior to running `nix-collect-garbage` (or just `nix-store --gc`) without any flags.
-
-> **Note**
->
-> Deleting previous configurations makes rollbacks to them impossible.
-
-These flags should be used with care, because they potentially delete generations of profiles used by other users on the system.
-
-## Locations searched for profiles
-
-`nix-collect-garbage` cannot know about all profiles; that information doesn't exist.
-Instead, it looks in a few locations, and acts on all profiles it finds there:
-
-1. The default profile locations as specified in the [profiles] section of the manual.
-
-2. > **NOTE**
-   >
-   > Not stable; subject to change
-   >
-   > Do not rely on this functionality; it just exists for migration purposes and may change in the future.
-   > These deprecated paths remain a private implementation detail of Nix.
-
-   `$NIX_STATE_DIR/profiles` and `$NIX_STATE_DIR/profiles/per-user`.
-
-   With the exception of `$NIX_STATE_DIR/profiles/per-user/root` and `$NIX_STATE_DIR/profiles/default`, these directories are no longer used by other commands.
-   `nix-collect-garbage` looks there anyways in order to clean up profiles from older versions of Nix.
-
-# Options
-
-These options are for deleting old [profiles] prior to deleting unreachable [store objects].
-
-- <span id="opt-delete-old">[`--delete-old`](#opt-delete-old)</span> / `-d`
-
-  Delete all old generations of profiles.
-
-  This is the equivalent of invoking [`nix-env --delete-generations old`](@docroot@/command-ref/nix-env/delete-generations.md#generations-old) on each found profile.
-
-- <span id="opt-delete-older-than">[`--delete-older-than`](#opt-delete-older-than)</span> *period*
-
-  Delete all generations of profiles older than the specified amount (except for the generations that were active at that point in time).
-  *period* is a value such as `30d`, which would mean 30 days.
-
-  This is the equivalent of invoking [`nix-env --delete-generations <period>`](@docroot@/command-ref/nix-env/delete-generations.md#generations-time) on each found profile.
-  See the documentation of that command for additional information about the *period* argument.

-
-  Keep deleting paths until at least *bytes* bytes have been deleted,
-  then stop. The argument *bytes* can be followed by the
