ryan4yin | 二花 d8b298019a refactor(shells): use native Home Manager Nushell and Nushell login on non-desktop hosts (#513)
* refactor(shells): use native Home Manager Nushell environment

Replace the Bash login-shell wrapper and hand-maintained Nushell PATH with programs.nushell.loadSessionVariables and home.sessionPath. Launch Nushell directly from Kitty, Ghostty, and Zed, with the macOS config-home override and Ghostty's vendor autoload directory.

Upstream feature: https://github.com/nix-community/home-manager/pull/9666

Assisted-by: DeepSeek Harness (deepseek-flash)

* feat(hosts): use Nushell as login shell on Ruby and Kana

Set the per-user shell explicitly and add Nushell to the system shell list. The system default shell and root remain unchanged.

* fix(ssh): preserve tuios session marker across SSH

Forward TUIOS_SESSION and accept it on NixOS sshd, so an SSH session opened from inside tuios does not auto-attach a nested remote tuios.

* feat(nixos): use Nushell login shell on non-desktop hosts

Enable the Nushell login shell through a shared module imported by the server and agent profiles. Desktop profiles continue to use Bash.

* fix(tuios): skip auto-attach in SSH sessions

Remote interactive shells now stay plain Nushell instead of starting a nested TUIOS when the SSH client is already inside a local TUIOS session. Local TUIOS auto-start is unchanged.

System hardening modules (kernel baseline, AppArmor, app sandboxes) live under ../hardening/.

Module Categories

1. Base Modules (base/)

Common configuration shared between NixOS and macOS:

  • System fonts and localization
  • Essential packages and tools
  • Basic security settings
  • User management
  • Package overlays

2. macOS Modules (darwin/)

macOS-specific configuration:

  • macOS applications and system settings
  • Security configurations tailored for macOS
  • SSH and system-level settings
  • Package compatibility fixes

3. NixOS Modules (nixos/)

Platform-specific NixOS configuration:

  • Base: Core system settings and services
  • Desktop: Desktop environment and GUI applications
  • Server: Server-specific optimizations and services

Usage

There is no automatic platform detection. Each host's entry under outputs/<system>/src/ lists its imports explicitly:

  • NixOS Systems: import nixos/ modules
  • macOS Systems: import darwin/ modules
  • Both: import base/ modules for shared configuration
