How to Create an Anaconda 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 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 product/run/install/product/pyanaconda/installclasses/ vim product/run/install/product/pyanaconda/installclasses/custom.py
Create new installclass, see Anaconda 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
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 here in the Lorax source tree.
