This installation tool will set up your computer with the Nix package manager. This will happen in a few stages:

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.
Show you what I am going to install and where. Then I will ask if you are ready to continue.
Create the system users (uids [30001..30032]) and groups (gid 30000) 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.
Perform the basic installation of the Nix files daemon.
Configure your shell to import special Nix Profile files, so you can use Nix.
Start the Nix daemon.

Would you like to see a more detailed list of what I will do? [y/n] y

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 /root
back up /etc/bash.bashrc to /etc/bash.bashrc.backup-before-nix
update /etc/bash.bashrc to include some Nix configuration
load and start a service (at /etc/systemd/system/nix-daemon.service and /etc/systemd/system/nix-daemon.socket) for nix-daemon

---- 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!

~~> 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.

~~> Setting up the build group nixbld

---- oh no! -------------------------------------------------------------------- It seems the build group nixbld already exists, but with the UID 998. This script can't really handle that right now, so I'm going to give up.

You can fix this by editing this script and changing the NIX_BUILD_GROUP_ID variable near the top to from 30000 to 998 and re-run.

We'd love to help if you need it.

Do you know if you previously customized a nix install, or perhaps already installed nix with your system package manager? If the latter, you'll need to remove that one before installing.

If the former, you should probably follow the uninstall instructions here: https://nixos.org/manual/nix/stable/installation/uninstall.html#linux
