Same username, different homeConfigurations

[esselius]

I use the same username on my home and work computers, but need to apply different home-manager config based on environment.

Got any tips for how to do this?

You don't need to have the same home.username as the name of the nix file it's inside of. You can have home-configurations/user-minimal.nix and home-configurations/user-full.nix and have them both have a home.username = "user";. I might need to make changes to make that work if you're using nixos-module version of home-manager

I'm using ezConfigs.nixos.hosts.adama.userHomeModules = [ "username" ]; yes :)

Is there a resolution to this? I am also interested in the same problem.

I've created a PR that should be able fix this issue, but when finishing it, I noticed a simpler solution. Or rather a solution that would not require extra maintenance on my part. The value of users.users.<user-config-name>.name need not be the same as users-config-name. If all that you need to do is have the same username, but use different configs, can't you write a nixos module like this:

users.users.my-minimal-config.name = "my-username";

and inside homeConfigurations/my-minimal-config.nix

{ pkgs, osConfig, ... }:
let users = osConfig.users.users;
in
{
  home = rec {
    username =
      if (users ? my-minimal-config) then
        users.my-minimal-config.name else
        "my-username";
    homeDirectory =
      if (users ? my-minimal-config) then
        users.my-minimal-config.home else
        (
          if pkgs.stdenv.isDarwin then
            "/Users/${username}" else
            "/home/${username}"
        );
  };
}

Would that solve your issue, or is the PR I made still necessary? I've always had my users-config-name be the same as the value of the name attribute, but I assume nixos lets you override that for a reason, and uses the value of name for everything that happens at the configuration "runtime".

The PR solves this for me!
