@michaelfuhr -

Correct and it won't work and install by default in our classroom environment. The systems don't technically meet the minimum requirements and it does fail the installation. We provide some "switches" to ignore the system check for memory and allowing the installer to run.

Specifically, when running the setup.sh script, you must use the 

-e ignore_preflight_errors=true

option along with that command.  This will tell it to "ignore" the hardware requirements - specifically the memory. Note that this isn't recommended for production systems and should only be used for the course. It should have been highlighted in the student guide with these instructions as well as an explanation of why we are doing that.
