Nix documentation does not describe how to set up a multi-user nix installation on a new user #11023

Problem

Hi,

I am working on a MacOS 14 machine that already has multi-user nix installed on it. I am trying to set up nix on a new user on that machine, but it seems there is no documentation about how to accomplish this, which seems counterintuitive since it is explicitly talking about a multi-user installation.

Proposal

Documentation should either describe that supporting multiple users is unsupported on a multi-user installation, or it should describe how to set up nix on a second user on a machine with nix already installed. Alternatively, the nix installer could be modified to offer to do this for you if it detects that multi-user nix is already installed.

It isn't documented because, speaking very generally, this should just work for every user you create as long as their shell is correctly sourcing one of the system-wide shell profiles.

Unclear from your report, but have you already tried this?

Yeah, from experience there are some caveats if you have messed with your system before. It may be worth an integration test case. I recently ranted about that we don't have the code setup for it yet, and added a few notes how we could get there: https://github.com/NixOS/nix/pull/10998#issuecomment-2211405429
