nix-configs

Nix configurations for various machines and software used at voidwarranties.

Barputer

Demo

A demo vm configuration for the barputer can be run using nix run .#barputer-demo. This will use https://github.com/voidwarranties/backtab and https://github.com/voidwarranties/tab-ui.

Deployment

Clone this repository to a local machine (with nix and flakes available) which we will use as the host to configure our deployment.

Prepare target (once)

1. Install NixOS on target machine
2. Enable nix-command and flakes: nix.settings.experimental-features = [ "nix-command" "flakes" ];
3. Permit root login over ssh: services.openssh.settings.PermitRootLogin = "yes";
4. Take note of any hardware specific changes you might apply, add them to /machines/barputer/default.nix if needed
5. Overwrite /machines/barputer/hardware-configuration.nix with the hardware-configuration.nix from the target machine

Prepare host (once)

1. Edit your ssh config and add the ip-address of the target machine:

   Host barputer
     Hostname 0.0.0.0
     User root
   

2. Use ssh-copy-id barputer to copy over the public key of your host to the target machine (this makes deployment easier)
3. Test the connection: ssh barputer

Deploying NixOS config

1. Use nix develop in the repository to enter the provided devshell
2. Deploy to target with barputer-deploy barputer boot. This will build the configuration on the target machine, make it the default boot option, but won't activate until next boot
