What do Build installation scripts automate during the installation process?

Build installation scripts are specifically designed to automate the execution of custom actions during the installation process. This means they can trigger specific tasks or functions that have been programmed to run automatically, ensuring that all necessary configurations and customizations are implemented without manual intervention. This automation helps streamline the installation, reduces the risk of errors, and ensures consistency across different environments.

In the context of the other options, while creating custom forms, executing scheduled tasks, and performing mass data entry are all important tasks in the NetSuite environment, they do not fall under the specific role of installation scripts. Creation of custom forms typically involves manual design and setup processes, scheduled task execution is more about running jobs at designated times, and mass data entry focuses on importing or entering large volumes of data into the system. Therefore, the primary focus of build installation scripts is effectively centered on automating custom actions for a smooth installation process.
