TODO

• Refactor how home-manager packages are installed. Currently GUI applications are installed for all systems (not-desirable).
• Add docker support.
• Setup git using home-manager.
• Add support for multiple architectures in devshells.
• Create a separate mediastation trait. Don't install those packages in workstation.
• Move home-manager config options out of base.nix
