<listitem>

|
<para>
|
|||
|
|
<emphasis>Declarative</emphasis>, where you declare what
|
|||
|
|
packages you want in your <literal>configuration.nix</literal>.
|
|||
|
|
Every time you run <literal>nixos-rebuild</literal>, NixOS will
|
|||
|
|
ensure that you get a consistent set of binaries corresponding
|
|||
|
|
to your specification.

|
<para>
|
|||
|
|
<emphasis>Ad hoc</emphasis>, where you install, upgrade and
|
|||
|
|
uninstall packages via the <literal>nix-env</literal> command.
|
|||
|
|
This style allows mixing packages from different Nixpkgs
|
|||
|
|
versions. It’s the only choice for non-root users.
