Switching to the Multi-user Installer
Welcome to the Multi-User Nix Installation
This installation tool will set up your computer with the Nix package
manager. This will happen in a few stages:
1. Make sure your computer doesn't already have Nix. If it does, I
will show you instructions on how to clean up your old install.
2. Show you what I am going to install and where. Then I will ask
if you are ready to continue.
3. Create the system users (uids [301..332]) and groups (gid 30000)
that the Nix daemon uses to run builds.
4. Perform the basic installation of the Nix files daemon.
5. Configure your shell to import special Nix Profile files, so you
can use Nix.
6. Start the Nix daemon.
Would you like to see a more detailed list of what I will do?
No TTY, assuming you would say yes :)
I will:
- make sure your computer doesn't already have Nix files
(if it does, I will tell you how to clean them up.)
- create local users (see the list above for the users I'll make)
- create a local group (nixbld)
- install Nix in to /nix
- create a configuration file in /etc/nix
- set up the "default profile" by creating some Nix-related files in
/var/root
- back up /etc/bashrc to /etc/bashrc.backup-before-nix
- update /etc/bashrc to include some Nix configuration
- back up /etc/zshrc to /etc/zshrc.backup-before-nix
- update /etc/zshrc to include some Nix configuration
- create a Nix volume and a LaunchDaemon to mount it
- create a LaunchDaemon (at /Library/LaunchDaemons/org.nixos.nix-daemon.plist) for nix-daemon

---- let's talk about sudo -----------------------------------------------------
This script is going to call sudo a lot. Normally, it would show you
exactly what commands it is running and why. However, the script is
run in a headless fashion, like this:
$ curl -L https://nixos.org/nix/install | sh
or maybe in a CI pipeline. Because of that, I'm going to skip the
verbose output in the interest of brevity.
If you would like to
see the output, try like this:
$ curl -L -o install-nix https://nixos.org/nix/install
$ sh ./install-nix
~~> Fixing any leftover Nix volume state
Before I try to install, I'll check for any existing Nix volume config
and ask for your permission to remove it (so that the installer can
start fresh). I'll also ask for permission to fix any issues I spot.
~~> Checking for artifacts of previous installs
Before I try to install, I'll check for signs Nix already is or has
been installed on this system.

---- Preparing a Nix volume ----------------------------------------------------
Nix traditionally stores its data in the root directory /nix, but
macOS now (starting in 10.15 Catalina) has a read-only root directory.
To support Nix, I will create a volume and configure macOS to mount it
at /nix.

disk3s7 was already unmounted
~~> Configuring /etc/fstab to specify volume mount options

---- oh no! --------------------------------------------------------------------
Oh no, something went wrong. If you can take all the output and open
an issue, we'd love to fix the problem so nobody else has this issue.
:(
We'd love to help if you need it.

Ah, sorry. I guess the conflict is probably the UID and not the username.
It looks like most people who’ve run into this on macOS have a SonosDMS user already at UID 301. Some people were no longer using Sonos, so they just removed that user and tried again.
If you’re still using it, the steps in this comment may help:
