4.3. Customizing the product name
To customize the product name, you must create a custom .buildstamp file. To do so, create a new .buildstamp file with the following content:
[Main]
Product=My Distribution
Version=10
BugURL=https://bugzilla.redhat.com/
IsFinal=True
Change My Distribution to the name which you want to display in the installer.
After you create the custom .buildstamp file, follow Creating a product.img file section to create a new product.img file containing your customizations, and the Creating custom boot images section to create a new bootable ISO file with your changes included.
