 # Uninstalling Nix
 
-## Multi User
-
-Removing a multi-user installation depends on the operating system.
-
-### Linux
-
-If you are on Linux with systemd:
-
-1. Remove the Nix daemon service:
-
-   ```console
-   sudo systemctl stop nix-daemon.service
-   sudo systemctl disable nix-daemon.socket nix-daemon.service
-   sudo systemctl daemon-reload
-   ```
-
-Remove files created by Nix:
+To uninstall Determinate Nix, use the uninstallation utility built into the [Determinate Nix Installer][installer]:
 
 ```console
-sudo rm -rf /etc/nix /etc/profile.d/nix.sh /etc/tmpfiles.d/nix-daemon.conf /nix ~root/.nix-channels ~root/.nix-defexpr ~root/.nix-profile ~root/.cache/nix
+$ /nix/nix-installer uninstall
 ```
 
-Remove build users and their group:
+If you're certain that you want to uninstall, you can skip the confirmation step:
 
 ```console
-for i in $(seq 1 32); do
-  sudo userdel nixbld$i
-done
-sudo groupdel nixbld
+$ /nix/nix-installer uninstall --no-confirm
 ```
 
-There may also be references to Nix in
-
-- `/etc/bash.bashrc`
-- `/etc/bashrc`
-- `/etc/profile`
-- `/etc/zsh/zshrc`
-- `/etc/zshrc`
-
-which you may remove.
-
-### macOS
-
-1. If system-wide shell initialisation files haven't been altered since installing Nix, use the backups made by the installer:
-
-   ```console
-   sudo mv /etc/zshrc.backup-before-nix /etc/zshrc
-   sudo mv /etc/bashrc.backup-before-nix /etc/bashrc
-   sudo mv /etc/bash.bashrc.backup-before-nix /etc/bash.bashrc
-   ```
-
-   Otherwise, edit `/etc/zshrc`, `/etc/bashrc`, and `/etc/bash.bashrc` to remove the lines sourcing `nix-daemon.sh`, which should look like this:
-
-   ```bash
-   # Nix
-   if [ -e '/nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh' ]; then
-     . '/nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh'
-   fi
-   # End Nix
-   ```
-
-2. Stop and remove the Nix daemon services:
-
-   ```console
-   sudo launchctl unload /Library/LaunchDaemons/org.nixos.nix-daemon.plist
-   sudo rm /Library/LaunchDaemons/org.nixos.nix-daemon.plist
-   sudo launchctl unload /Library/LaunchDaemons/org.nixos.darwin-store.plist
-   sudo rm /Library/LaunchDaemons/org.nixos.darwin-store.plist
-   ```
-
-   This stops the Nix daemon and prevents it from being started next time you boot the system.
-
-3. Remove the `nixbld` group and the `_nixbuildN` users:
-
-   ```console
-   sudo dscl . -delete /Groups/nixbld
-   for u in $(sudo dscl . -list /Users | grep _nixbld); do sudo dscl . -delete /Users/$u; done
-   ```
-
-   This will remove all the build users that no longer serve a purpose.
-
-4. Edit fstab using `sudo vifs` to remove the line mounting the Nix Store volume on `/nix`, which looks like
-
-   ```
-   UUID=<uuid> /nix apfs rw,noauto,nobrowse,suid,owners
-   ```
-   or
-
-   ```
-   LABEL=Nix\040Store /nix apfs rw,nobrowse
-   ```
-
-   by setting the cursor on the respective line using the arrow keys, and pressing `dd`, and then `:wq` to save the file.
-
-   This will prevent automatic mounting of the Nix Store volume.
-
-5. Edit `/etc/synthetic.conf` to remove the `nix` line.
-   If this is the only line in the file you can remove it entirely:
-
-   ```bash
-   if [ -f /etc/synthetic.conf ]; then
-     if [ "$(cat /etc/synthetic.conf)" = "nix" ]; then
-       sudo rm /etc/synthetic.conf
-     else
-       sudo vi /etc/synthetic.conf
-     fi
-   fi
-   ```
-
-   This will prevent the creation of the empty `/nix` directory.
-
-6. Remove the files Nix added to your system, except for the store:
-
-   ```console
-   sudo rm -rf /etc/nix /var/root/.nix-profile /var/root/.nix-defexpr /var/root/.nix-channels ~/.nix-profile ~/.nix-defexpr ~/.nix-channels
-   ```
-
-
-7. Remove the Nix Store volume:
-
-   ```console
-   sudo diskutil apfs deleteVolume /nix
-   ```
-
-   This will remove the Nix Store volume and everything that was added to the store.
-
-   If the output indicates that the command couldn't remove the volume, you should make sure you don't have an _unmounted_ Nix Store volume.
-   Look for a "Nix Store" volume in the output of the following command:
-
-   ```console
-   diskutil list
-   ```
-
-   If you _do_ find a "Nix Store" volume, delete it by running `diskutil apfs deleteVolume` with the store volume's `diskXsY` identifier.
-
-   If you get an error that the volume is in use by the kernel, reboot and immediately delete the volume before starting any other process.
-
-> **Note**
->
-> After you complete the steps here, you will still have an empty `/nix` directory.
-> This is an expected sign of a successful uninstall.
-> The empty `/nix` directory will disappear the next time you reboot.
->
-> You do not have to reboot to finish uninstalling Nix.
-> The uninstall is complete.
-> macOS (Catalina+) directly controls root directories, and its read-only root will prevent you from manually deleting the empty `/nix` mountpoint.
