Host and Home Manager Flake

• Manage multiple hosts (NixOS VM, Macbook)
• Manage dotfiles, configurable per host

Structure

• hardware/ namespaced hardware-configuration.nix files
• machines/ namespaced configuration.nix files
• users/
  • namespaced user accounts and home-manager configs
  • shared dotfiles
  • shared common home config
• lib/ library funcs

Hosts

• vm-aarch64
  • NixOS VM on personal Macbook M1

How do I ...

Rebuild a host?

Inside this flake dir, run switch and specify the host (defined in flake.nix outputs):

sudo nixos-rebuild switch --flake ".#${host}"

Setup Mac Home?

Home Manager is installed standalone on personal Macbook M1. A separate home.nix file exists to configure just the user environment there. Run switch and point it to this file:

home-manager switch -f users/alex-darwin/home.nix -b backup

Once darwin-nix is setup, this will change.
