there is a chance this is an artifact from my using an image from a mis-matched project

and having to update /opt/gcp/etc/gcp-config.sh

nope - was able to clean and recreate the issue even with an accurate gcp-config.sh

Is there an easy way to make this a condition in the systemd service file, or should the python script just while loop with sleep until that file exists?? (a quick look indicates ConditionPathExists for systemd is only checked once, and does not loop - so I'm guessing we bake more of this into the python activator)
