nixos-config

My Nixos flake configs. Not much to say, for now it's fairly self explanatory if you know NixOS.

I have a terrible memory, day-to-day commands are in CHEATSHEET.md.

Reinstalling an existing host

1. Install minimal NixOS, clone this repo and cd into it.

2. Overwrite the host's hardware scan with the one the installer just generated (picks up any disk-layout changes, or new hardware):

   HOST=gammelerik
   cp /etc/nixos/hardware-configuration.nix hosts/$HOST/
   

3. Build:

   ./rebuild switch $HOST
   

4. Reboot, then commit if the hardware scan changed.

Adding a new host

1. Install minimal NixOS, then clone this repo and cd into it.

2. Copy the install's hardware scan and an existing host as a starting point:

   HOST=mynewbox
   mkdir -p hosts/$HOST
   cp /etc/nixos/hardware-configuration.nix hosts/$HOST/
   cp hosts/gammelerik/configuration.nix hosts/$HOST/configuration.nix
   

   Edit configuration.nix — at least set networking.hostName.

3. Add a nixosConfigurations.$HOST entry in flake.nix with the modules you want (always common.nix, then desktop, sway, hyprland, virtualization etc. as needed).

4. git add the new files (Nix ignores untracked files), then build:

   git add hosts/$HOST flake.nix
   ./rebuild switch $HOST
   

5. Reboot, then commit.
