%entities; ]> The easiest way to get started is if the machine is already in Vuizvui so there is a channel available. You can have a look at the list of channels to check whether a channel exists for the machine you want to install. So let's say you want to install the machine labtop which has the channel attribute channels.machines.labnet.labtop First you need to add the channel for the root user of your current system using the following commands: nix-channel --add vuizvui nix-channel --update Notice the vuizvui argument at the end of the first command. This makes the channel available as <vuizvui> in the search path of the current system. For the first installation the NIX_PATH isn't correctly set and will be set to include the vuizvui channel after you've switched to the configuration for the first time. Next put the following in your /etc/nixos/configuration.nix: (import <vuizvui/machines> {}).labnet.labtop.use Of course you need to replace labnet.labtop with the attribute of your machine. Now in order to do the first build and activation of the configuration, you need to issue the following command as root: nixos-rebuild switch
