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 [351..382]) and groups (gid 350)
   that the Nix daemon uses to run builds. To create system users
   in a different range, exit and run this tool again with
   NIX_FIRST_BUILD_UID set.

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?

---- let's talk about sudo -----------------------------------------------------
This script is going to call sudo a lot. Every time I do, it'll
output exactly what it'll do, and why.

Just like this:

---- sudo execution ------------------------------------------------------------
I am executing:

    $ sudo echo

to demonstrate how our sudo prompts look


This might look scary, but everything can be undone by running just a
few commands. I used to ask you to confirm each time sudo ran, but it
was too many times. Instead, I'll just ask you this one time:

Can I use sudo?
[y/n] y

Yay! Thanks! Let's get going!

~~> 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.

---- Found existing Nix volume -------------------------------------------------
  special:	disk3s7
     uuid:	CA069A52-A1A5-4087-A83D-CBC1667E688E
encrypted:	yes

---- sudo execution ------------------------------------------------------------

I am executing:

    $ sudo security find-generic-password -s CA069A52-A1A5-4087-A83D-CBC1667E688E -w

to confirm keychain has a password that unlocks this volume

---- sudo execution ------------------------------------------------------------
I am executing:

    $ sudo /usr/sbin/diskutil apfs unlockVolume disk3s7 -verify -stdinpassphrase -user CA069A52-A1A5-4087-A83D-CBC1667E688E

to confirm the password actually unlocks the volume

Password:Password:

sudo: a password is required
sudo: a password is required

---- warning! ------------------------------------------------------------------

This volume is encrypted, but I don't see a password to decrypt it.
The quick fix is to let me delete this volume and make you a new one.
If that's okay, enter your (sudo) password to continue. If not, you
can ensure the decryption password is in your system keychain with a
"Where" (service) field set to this volume's UUID:
  CA069A52-A1A5-4087-A83D-CBC1667E688E

Can I delete this volume?
[y/n] y

Enter your password to delete this volume:

---- sudo execution ------------------------------------------------------------
I am executing:

    $ sudo /usr/sbin/diskutil unmount force disk3s7

to unmount the Nix volume

Password:
Volume Nix Store on disk3s7 force-unmounted

---- sudo execution ------------------------------------------------------------
I am executing:

    $ sudo /usr/sbin/diskutil apfs deleteVolume disk3s7

to delete the Nix volume

Password:
Started APFS operation
Deleting APFS Volume from its APFS Container
Unmounting disk3s7
Erasing any xART session referenced by CA069A52-A1A5-4087-A83D-CBC1667E688E
Deleting Volume
Removing any Preboot and Recovery Directories
Finished APFS operation

During install, I add 'nix' to /etc/synthetic.conf, which instructs
macOS to create an empty root directory for mounting the Nix volume.

Nix isn't the only thing in /var/folders/vh/3pfk9szd6pl3cm80jhlgyqs80000gn/T/tmp.Thd9i6XTZ3/synthetic.conf.edit,
but I think I know how to edit it out.
Here's the diff:
run	private/var/run
nix
Does the change above look right?
[y/n] y


---- sudo execution ------------------------------------------------------------
I am executing:

    $ sudo cp /etc/synthetic.conf /var/folders/vh/3pfk9szd6pl3cm80jhlgyqs80000gn/T/tmp.Thd9i6XTZ3/synthetic.conf.edit

remove nix from /var/folders/vh/3pfk9szd6pl3cm80jhlgyqs80000gn/T/tmp.Thd9i6XTZ3/synthetic.conf.edit

Password:
During install, I add '/nix' to /etc/fstab so that macOS knows what
mount options to use for the Nix volume.
Password:
Can I remove /etc/fstab?
[y/n] y


---- sudo execution ------------------------------------------------------------
I am executing:

    $ sudo rm /etc/fstab

to remove /etc/fstab

Password:

The installer adds a LaunchDaemon to mount your Nix volume: org.nixos.darwin-store
Can I remove it?
[y/n] y


---- sudo execution ------------------------------------------------------------
I am executing:

    $ sudo launchctl bootout system/org.nixos.darwin-store

to terminate the daemon

Password:

---- sudo execution ------------------------------------------------------------
I am executing:

    $ sudo rm /Library/LaunchDaemons/org.nixos.darwin-store.plist

to remove the daemon definition

~~> 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.

~~> Creating a Nix volume

---- sudo execution ------------------------------------------------------------
I am executing:

    $ sudo /usr/sbin/diskutil unmount force disk3s7

to ensure the Nix volume is not mounted

Password:
Unmount failed for disk3s7

~~> Configuring /etc/fstab to specify volume mount options

---- sudo execution ------------------------------------------------------------
I am executing:

    $ sudo /usr/sbin/vifs

to add nix to fstab

Password:

~~> Encrypt the Nix volume

---- sudo execution ------------------------------------------------------------
I am executing:

    $ sudo /usr/sbin/diskutil mount Nix Store

to mount your Nix volume for encrypting

Password:
Failed to find disk Nix Store

---- 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.
