For those who did not understand the purpose of the two linux commands I posted, they go in the RUNME.sh file, or better yet, the payload dropped by data.tar.gz. They do nothing unless the folder or file are missing, in which case they are created. All automatic, with no manual steps or worry by the end user. The USER does not need extra steps. Those are part of the payload...
Here they are again:
mkdir -p /mnt/us/diagnostic_logs
touch /mnt/us/diagnostic_logs/device_info.xml
