<title>Keeping NixOS up to date</title>
<para>The currently best way to keep your NixOS installation up to
date is to track the NixOS Subversion repository. You should replace
the static NixOS/Nixpkgs sources installed in
<filename>/etc/nixos</filename> with a Subversion checkout. The
program <command>nixos-checkout</command> does that for you (and it
also installs Subversion into your current profile).</para>
date is to track the NixOS Subversion repository. The program
<command>nixos-checkout</command> does that for you. It will
check if the NixOS/NixPkgs sources are present and if they are under a
version control system (VCS) before updating them to the latest version. If your
sources are not under a VCS, then you can rename them before
running <command>nixos-checkout</command> which will checkout the sources.</para>
<para>To build the latest and greatest, do
<screen>
$ svn up /etc/nixos/nixos
$ svn up /etc/nixos/nixpkgs
$ nixos-checkout
$ nixos-rebuild switch</screen>
(Or instead of <literal>switch</literal>, use any of the alternatives
shown in <xref linkend="sec-changing-config"/>.)</para>
<para>To customize your VCS or to handle more repositories with
<command>nixos-checkout</command>, you can have a look at the
options <option>installer.repos.nixos</option>
and <option>installer.repos.nixpkgs</option>.</para>
