Automatic Configuration of Solaris OCI Guests

Once you've gone through the basics of setting up an Oracle Solaris guest on Oracle Cloud Infrastructure (OCI) covered in my previous post, you will likely wonder how you can customize them automatically at launch. 

You can always create specific custom images by hand, but that has two problems: you're doing a lot of work by hand, and then you have to manage the custom images as well; once created, they become objects with a lifecycle of their own. 

The natural desire of system admins is to write some scripts to automate the work, and then run those scripts at first boot.
