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?

error: failed to bootstrap /nix
If you enabled FileVault after booting, this is likely a known issue
with macOS that you'll have to reboot to fix. If you didn't enable FV,
though, please open an issue describing how the system that you see
this error on was set up.

We'd love to help if you need it.
