<title>Testing the Installer</title>
<para>
Building, burning, and booting from an installation CD is rather tedious, so
here is a quick way to see if the installer works properly:

Manual: Explicitly mark commands that require to be run as root (#15589) * manual: Mark commands that require root Mark every command that requires to be run as root by prefixing them with '#' instead of '$'. * manual: Add note about commands that require root

# mount -t tmpfs none /mnt
nixos-install: Make compatible with Nix 2.0 The use of Nix 2.0 significantly simplifies the installer, since we can just pass a different store URI (--store /mnt) - it's no longer needed to set up a chroot environment for the build, and to bootstrap Nix into the chroot. Also, commands that need to run in the installation (namely boot loader installation and setting a root password) are now executed using nixos-enter. This also removes the need for nixos-prepare-root since any required initialisation is done by Nix or by the activation script.
