  • Build and switch to the new configuration, making it the boot default:

sudo nixos-rebuild switch

  • Build and switch to the new configuration, making it the boot default and naming the boot entry:

sudo nixos-rebuild switch {{[-p|--profile-name]}} {{name}}

  • Build and switch to the new configuration, making it the boot default and installing updates:

sudo nixos-rebuild switch --upgrade

  • Rollback changes to the configuration, switching to the previous generation:

sudo nixos-rebuild switch --rollback

  • Build the new configuration and make it the boot default without switching to it:

sudo nixos-rebuild test

  • Build the configuration and open it in a virtual machine:

sudo nixos-rebuild build-vm
