Further installation instructions
Install
The xmod configuration also contains my Home Manager configuration using the NixOS module, so it can easily be tested with a single command.
nixos-rebuild switch --flake github:gvolpe/nix-config#xmod
Or you can test it directly on a QEMU virtual machine, though it has its limitations in terms of graphics.
nixos-rebuild build-vm --flake github:gvolpe/nix-config#xmod
./result/bin/run-xmod-amd-vm
Having both NixOS and Home Manager configurations combined makes it easier to quickly install it on a new machine, but my preference is to have both separate, as my Home Manager configuration changes more often than that of the NixOS one, which can result in multiple (unwanted) generations at boot time.
Managing the different Home Manager generations in isolation makes this way easier for me.
NixOS
The NixOS configuration can be installed by running the following command.
nixos-rebuild switch --flake github:gvolpe/nix-config#thinkpad-x1
Beware that the hardware-configuration.nix file is the result of the hardware scan of the specific machine and might not be suitable for yours.
Home Manager
A fresh install requires the creation of certain directories (see what the switch script does). However, if you omit those steps, the entire HM configuration can also be built as any other flake.
nix build github:gvolpe/nix-config#homeConfigurations.xmonad-edp.activationPackage
result/activate
