Q: createinstallmedia doesnt install .IAProductInfo ... why?

I tried to create a USB Install device using the instructions found here

Create a bootable installer for OS X - Apple Support

 

Basically run the "createinstallmedia" command with the right options.

 

When I boot using that USB device it seems to run... but then it stops and boots using the Internet recovery mode (there is no recovery partition on my Mac).

 

I had a USB Flash device that I made earlier in the year and the only difference was the file ".IAProductInfo"

 

When I copied that file onto the new USB Flash everything worked.

 

Why?

 

How do I get it working correctly?
