IIAB/local vars big.yml
Please also see FAQ.IIAB.IO, specifically: "What is local_vars.yml and how do I customize it?"
Here is an example BIG-sized
/etc/iiab/local_vars.yml including a full suite of almost 20 Internet-in-a-Box (IIAB) server apps — to help implementers explore and remix different LMS choices and educational apps: https://github.com/iiab/iiab/blob/master/vars/local_vars_big.yml
WARNING: on small Internet-in-a-Box devices, it's common to want a "Rapid Power Off" button clickable by all users in a clinic or home. Conversely, schoolteachers commonly want to disable this Power Off button, changing the "allow_apache_sudo" flag to "False".
