nixos-configuration

My personal NixOS Configuration (most of it anyway)

Disclaimer

You might run into modules, which are not imported by any of my current installations, therefore it might even throw some error during rebuild if you just copy-paste it.

Reusable parts

Importing certificates

To make it easier to add certificates the commons/nixos/certs.nix is created to import all certificates added to the certs folder

Java jks setup with custom certificates

commons/java.nix contains a hacky way to always use custom certificates added to the config. (Works with the above helper)

Btrfs snapshots with snapper

The config in disk-setup/btrfs-with-snapper.nix defines a system installed on btrfs subvolumes and uses snapperd to create snapshots automatically for easier.

Firefox Opener

The config in commons/firefox.nix defines some nice support for firefox containers, so you can choose for every link clicked outside of firefox (like a chat application), that what container will be used for them interactively.

{
  zsedem.firefox-opener = {
    enable = true;
    containers = [ # You might add only the containers, which you want to use for pages from external applications
      { name = "Work"; color = "purple"; }  # Color is used in the interactive page
      { name = "Personal"; color = "red"; }
    ];
    host-mapping = {
      "www.fastmail.com" = "Personal";
      "github.com" = "Work";
    };
  };
}

Using this repository as a channel (as I use it on my personal machine)

When setting up the configuration.nix in the installation process:

1. Add Channels

# nix-channel --add https://github.com/NixOS/nixos-hardware/archive/master.tar.gz nixos-hardware
# nix-channel --add https://nixos.org/channels/nixos-unstable nixos-unstable
# nix-channel --add https://github.com/zsedem/nixos-configuration/archive/refs/heads/master.tar.gz zsedem-config
# nix-channel --update

2. Create a configuration.nix

{ config, ... }:

{
  imports = [
    <zsedem-config/configuration.nix>
    <zsedem-config/disk-setup/btrfs-with-snapper.nix>
    <zsedem-config/hardware/t470.nix>
  ];

  boot.initrd.luks.devices."BtrfsRoot".device = "/dev/nvme0n1p2";
  zsedem.btrfs-root = "/dev/mapper/BtrfsRoot";
  zsedem.certificatesFolder = ./certs;

  fileSystems."/boot" = { ... };

  zsedem.zoom = true;
  zsedem.kafka = true;
  programs.java.enable = true;
}
