|
<para>This section describes how to add additional packages to your
|
|||
|
|
system. NixOS has two distinct styles of package management:
|
|||
|
|
|
|||
|
|
<itemizedlist>
|
|||
|
|
|
|||
|
|
<listitem><para><emphasis>Declarative</emphasis>, where you declare
|
|||
|
|
what packages you want in your
|
|||
|
|
<filename>configuration.nix</filename>. Every time you run
|
|||
|
|
<command>nixos-rebuild</command>, NixOS will ensure that you get a
|
|||
|
|
consistent set of binaries corresponding to your
|
|||
|
|
specification.</para></listitem>
|
|||
|
|
|
|||
|
|
<listitem><para><emphasis>Ad hoc</emphasis>, where you install,
|
|||
|
|
upgrade and uninstall packages via the <command>nix-env</command>
|
|||
|
|
command. This style allows mixing packages from different Nixpkgs
|
|||
|
|
versions. It’s the only choice for non-root
|
|||
|
|
users.</para></listitem>
