nixos login: root (automatic login)
User not known to the underlying authentication module

I'm amazed that that is possible.

I'm really hoping some of you have the technical know-how to help me here, because I really don't want to uninstall NixOs!

For simplicity, all I want is a global install of rustup or oxalica/rust-overlay so I can write Rust code again!

I've got Rust compiling in shell.nix but I'm keen on a global install (I'm a full time Rust engineer) that plays nice with my RustRover IDE.

Setup:

• OS: NixOs
• Flakes: enabled
• IDE: RustRover

Can someone please please help me? I took two days off this week to contribute to OSS and all I've managed is to beat my head against a Nix wall 🙏

Oh, forgot to add, my "rustup environment.systemPackages" doesn't work because:

  The system library `openssl` required by crate `openssl-sys` was not found.
  The file `openssl.pc` needs to be installed and the PKG_CONFIG_PATH environment variable must contain its parent directory.
  The PKG_CONFIG_PATH environment variable is not set.

  HINT: if you have installed the library, try setting PKG_CONFIG_PATH to the directory containing `openssl.pc`.

  Could not find directory of OpenSSL installation, and this `-sys` crate cannot

  trouble finding it,  you can set the `OPENSSL_DIR` environment variable for the

  Make sure you also have the development packages of openssl installed.
  For example, `libssl-dev` on Ubuntu or `openssl-devel` on Fedora.

  If you're in a situation where you think the directory *should* be found
  automatically, please open a bug at https://github.com/sfackler/rust-openssl
  and include information about your system as well as this message.
