My NixOS Configurations

NixOS is an advanced GNU/Linux distribution featuring declarative configuration, reproducible builds and atomic upgrades. You can learn more at nixos.org.

In this repository are the configurations of my NixOS machines.

You can find the configurations from other people in the nixos.wiki.

Usage

My workflow with this code is to rsync it to the machine and symlink the system configuration.

[davidak@X230:~]$ rsync -ah --delete --progress /home/davidak/code/nixos-config/ root@nas.lan:nixos/
[root@nixos:~]# rm /etc/nixos/configuration.nix
[root@nixos:~]# ln -s /root/nixos/machines/compaq_dc7800/configuration.nix /etc/nixos/configuration.nix
[root@nixos:~]# nixos-rebuild switch

This way i can test a change before committing it to the git repository. To update the configuration, just use the first and last command.

For new machines, follow the install instructions in the manual and extend it with inspirations from the machines here.

I use the latest stable release nixos channel to have a reliable system and the nixos-unstable channel to get the latest version for some packages. I also use nixos-hardware channel for hardware specific settings and home-manager for user specific configuration.

Add the channels with this commands:

nix-channel --add https://nixos.org/channels/nixos-20.09 nixos
nix-channel --add https://nixos.org/channels/nixos-unstable nixos-unstable
nix-channel --add https://github.com/NixOS/nixos-hardware/archive/master.tar.gz nixos-hardware
nix-channel --add https://github.com/rycee/home-manager/archive/release-20.09.tar.gz home-manager
nix-channel --update

(execute as root or with sudo)
