I've suffered a catastrophic failure with my controller's SD card, and am in the midst of rebuilding it.
Rather than merely restore from backup and partly for learning, I've taken it upon myself to re-configure the cluster and all nodes as desired from base image via Ansible. This includes SSH configuration, wireless networks, Docker, mpiexec configuration, etc.
Rather than download (and re-download, in the future) all five individual CNAT images, is it possible to flash only a single node image to each Pi Zero, with it customized per Pi by appending" quiet init=/sbin/reconfig-clusterctrl TYPE" to each cmdline.txt file? In other words, are all the node images functionally the same?
Thanks Chris, for the wonderful genius placed in your beautiful products- I use them on a regular basis in all aspects of my work.
