<listitem><para>Certain packages in Nixpkgs are now
user-configurable through a configuration file, i.e., without having
to edit the Nix expressions in Nixpkgs. For instance, the Firefox
provided in the Nixpkgs channel is built without the RealPlayer
plugin (for legal reasons). Previously, you could easily enable
RealPlayer support by editing the call to the Firefox function in
<filename>all-packages.nix</filename>, but such changes are not
respected when Firefox is subsequently updated through the Nixpkgs
channel.</para>
<para>The Nixpkgs configuration file (found in
<filename>~/.nixpkgs/config.nix</filename> or through the
<envar>NIXPKGS_CONFIG</envar> environment variable) is an attribute
set that contains configuration options that
<filename>all-packages.nix</filename> reads and uses for certain
packages. For instance, the following configuration file:
<programlisting>
{
firefox = {
enableRealPlayer = true;
};
}</programlisting>
persistently enables RealPlayer support in the Firefox
build.</para>

<listitem><para>It has also become much easier to experiment with
changes to the <literal>stdenv</literal> setup script (which notably
contains the generic builder). Since edits to
<filename>pkgs/stdenv/generic/setup.sh</filename> trigger a rebuild
of <emphasis>everything</emphasis>, this was formerly quite painful.
But now <literal>stdenv</literal> contains a function to
“regenerate” <literal>stdenv</literal> with a different setup
script, allowing the use of a different setup script for specific
packages:
<programlisting>
pkg = import <replaceable>...</replaceable> {
stdenv = stdenv.regenerate ./my-setup.sh;

}</programlisting>
