= Creating a Product image
Anaconda supports several ways to load new code at runtime.

Passing `inst.updates=<url>` is one way to do this and is documented on the file:/anaconda/anaconda_updates.html[updates] page.

Another is to include a product.img in the install tree, inside the `/images/` directory.
It will be applied at runtime and can overwrite any file on the system, just like the updates.img.
One use for a product.img is to add a new installclass to Anaconda.
A product image for a new installclass can be created from a directory of files like this:
----
mkdir -p product/run/install/product/pyanaconda/installclasses/
vim product/run/install/product/pyanaconda/installclasses/custom.py
----

Create new installclass, see link:https://github.com/rhinstaller/anaconda/tree/master/pyanaconda/installclasses[Anaconda code] for examples.

Now you can create the product.img:
----
cd product/
find . | cpio -c -o | pigz -9cv > ../product.img
----
Now you can include product.img in the tree, inside `/images/`.
Alternatively you can now use lorax to create product.img as part of the boot.iso creation process.
This is supported by lorax-21.27-1 and is documented link:http://rhinstaller.github.io/lorax/product-images.html[here] in the Lorax source tree.
