# NixOS
|
|
|
|
* There is controversy about flakes, rather use channels (e.g. with niv)
|
|
|
|
## Build and Switch
|
|
|
|
* https://nixos.wiki/wiki/Nixos-rebuild
|
|
|
|
Directly change to new config, make it default:
|
|
|
|
```shell
|
|
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:
|
|
|
|
```shell
|
|
sudo nix-channel --list
|
|
#=> nixos https://nixos.org/channels/nixos-23.05
|
|
```
|
|
|
|
Use the corresponding branch:
|
|
|
|
```shell
|
|
niv add nix-community/home-manager -n home-manager -b release-23.05
|
|
```
|
