NixOS
- There is controversy about flakes, rather use channels (e.g. with niv)
Build and Switch
Directly change to new config, make it default:
sudo nixos-rebuild -I nixos-config=yodaTux/configuration.nix switch
Install Home Manager with niv
Easy dependency management for Nix projects.
Nix is a very powerful tool for building code and setting up environments. niv complements it by making it easy to describe and update remote dependencies (URLs, GitHub repos, etc). It is a simple, practical alternative to Nix flakes.
[Home Manager] allows declarative configuration of user specific (non global) packages and dotfiles.
To avoid breaking users' configurations, Home Manager is released in branches corresponding to NixOS releases ( e.g.
release-23.05).Home Manager provides both the channel-based setup and the flake-based one.
Check your channel:
sudo nix-channel --list
#=> nixos https://nixos.org/channels/nixos-23.05
Use the corresponding branch:
niv add nix-community/home-manager -n home-manager -b release-23.05
