Just a collection of commands an config snippets I use to work with nixos.
Start a shell and install package from local nixpkgs repo:
nix-shell -I nixpkgs=./nixpkgs/ -p package1 package2

Create a container from a configuration.nix
sudo nixos-container create container-name --config-file /path/configuration.nix
Experimental nixos features in nixos-rebuild
nixos-rebuild --option experimental-features "nix-command flakes" switch
error: file ’nixos-config’ was not found in the Nix search path (add it using $NIX_PATH or -I)
nix-channel --update
Call flake by name
nixos-rebuild switch --flake .#witness
