<title>Replace Modules</title>
<para>
Modules that are imported can also be disabled. The option
declarations, config implementation and the imports of a disabled
module will be ignored, allowing another to take it's place. This
can be used to import a set of modules from another channel while
keeping the rest of the system on a stable release.
</para>
<para>
<literal>disabledModules</literal> is a top level attribute like
<literal>imports</literal>, <literal>options</literal> and
<literal>config</literal>. It contains a list of modules that will
be disabled. This can either be the full path to the module or a
string with the filename relative to the modules path (eg.
&lt;nixpkgs/nixos/modules&gt; for nixos).
</para>
<para>
This example will replace the existing postgresql module with the
version defined in the nixos-unstable channel while keeping the rest
of the modules and packages from the original nixos channel. This
only overrides the module definition, this won't use postgresql from
nixos-unstable unless explicitly configured to do so.

This example shows how to define a custom module as a replacement
for an existing module. Importing this module will disable the
original module without having to know it's implementation details.
