Issue

• Attempting to create a custom installer of Red Hat Enterprise Linux 7.1 and have created a product.img as instructed in the Desktop Migration Guide
• The images are successfully being over-ridden however the installer text is not.
• Switching TTY's and viewing the anaconda.log I see it say

22:37:21,887 INFO anaconda: MyDistro is the highest priority installclass, using it.

• However, the installer text still says "RED HAT ENTERPRISE LINUX 7.1 INSTALLATION". Is this correct? It was supposed to overridde the installer text once you include a custom.py file.
• The custom.py that has been places in product/run/install/product/pyanaconda/installclasses:
