-# Installing a Binary Distribution
-
-> **Updating to macOS 15 Sequoia**
->
-> If you recently updated to macOS 15 Sequoia and are getting
-> ```console
-> error: the user '_nixbld1' in the group 'nixbld' does not exist
-> ```
-> when running Nix commands, refer to GitHub issue [NixOS/nix#10892](https://github.com/NixOS/nix/issues/10892) for instructions to fix your installation without reinstalling.
-
-To install the latest version Nix, run the following command:
-
-```console
-$ curl -L https://nixos.org/nix/install | sh
-```
-
-This performs the default type of installation for your platform:
-
-- [Multi-user](#multi-user-installation):
-  - Linux with systemd and without SELinux
-  - macOS
-
-The installer can configured with various command line arguments and environment variables.
-To show available command line flags:
-
-```console
-$ curl -L https://nixos.org/nix/install | sh -s -- --help
-```
-
-To check what it does and how it can be customised further, [download and edit the second-stage installation script](#installing-from-a-binary-tarball).
-
-# Installing a pinned Nix version from a URL
-
-Version-specific installation URLs for all Nix versions since 1.11.16 can be found at [releases.nixos.org](https://releases.nixos.org/?prefix=nix/).
-The directory for each version contains the corresponding SHA-256 hash.
-
-All installation scripts are invoked the same way:
-
-```console
-$ export VERSION=2.19.2
-$ curl -L https://releases.nixos.org/nix/nix-$VERSION/install | sh
-```
-
-# Multi User Installation
-
-The multi-user Nix installation creates system users and a system service for the Nix daemon.
-
-Supported systems:
-
-- Linux running systemd, with SELinux disabled
-- macOS
-
-To explicitly instruct the installer to perform a multi-user installation on your system:
-
-```console
-$ bash <(curl -L https://nixos.org/nix/install) --daemon
-```
-
-You can run this under your usual user account or `root`.
-The script will invoke `sudo` as needed.
-
-# Installing from a binary tarball
-
-You can also download a binary tarball that contains Nix and all its dependencies:
-- Choose a [version](https://releases.nixos.org/?prefix=nix/) and [system type](../development/building.md#platforms)
-- Download and unpack the tarball
-- Run the installer
-
-> **Example**
->
-> ```console
-> $ pushd $(mktemp -d)
-> $ export VERSION=2.19.2
-> $ export SYSTEM=x86_64-linux
-> $ curl -LO https://releases.nixos.org/nix/nix-$VERSION/nix-$VERSION-$SYSTEM.tar.xz
-> $ tar xfj nix-$VERSION-$SYSTEM.tar.xz
-> $ cd nix-$VERSION-$SYSTEM
-> $ ./install
-> $ popd
-> ```
-
-The installer can be customised with the environment variables declared in the file named `install-multi-user`.
-
-## Native packages for Linux distributions
-
-The Nix community maintains installers for some Linux distributions in their native packaging format(https://nix-community.github.io/nix-installers/).

-
-We believe we have ironed out how to cleanly support the read-only root file system
-on modern macOS. New installs will do this automatically.
-
-This section previously detailed the situation, options, and trade-offs,
-but it now only outlines what the installer does. You don't need to know
-this to run the installer, but it may help if you run into trouble:
-
-- create a new APFS volume for your Nix store
-- update `/etc/synthetic.conf` to direct macOS to create a "synthetic"
-  empty root directory to mount your volume
-- specify mount options for the volume in `/etc/fstab`
-  - `rw`: read-write
-  - `noauto`: prevent the system from auto-mounting the volume (so the
-    LaunchDaemon mentioned below can control mounting it, and to avoid
-    masking problems with that mounting service).
-  - `nobrowse`: prevent the Nix Store volume from showing up on your
-    desktop; also keeps Spotlight from spending resources to index
-    this volume
-  <!-- TODO:
-  - `suid`: honor setuid? surely not? ...
-  - `owners`: honor file ownership on the volume
-
-    For now I'll avoid pretending to understand suid/owners more
-    than I do. There've been some vague reports of file-ownership
-    and permission issues, particularly in cloud/VM/headless setups.
-    My pet theory is that this has something to do with these setups
-    not having a token that gets delegated to initial/admin accounts
-    on macOS. See scripts/create-darwin-volume.sh for a little more.
-
-    In any case, by Dec 4 2021, it _seems_ like some combination of
-    suid, owners, and calling diskutil enableOwnership have stopped
-    new reports from coming in. But I hesitate to celebrate because we
-    haven't really named and catalogued the behavior, understood what
-    we're fixing, and validated that all 3 components are essential.
-  -->
-- if you have FileVault enabled
-    - generate an encryption password
-    - put it in your system Keychain
-    - use it to encrypt the volume
-- create a system LaunchDaemon to mount this volume early enough in the
-  boot process to avoid problems loading or restoring any programs that
-  need access to your Nix store
