1. If there is nobody who knows how the previous conf mgmt system was configured, or how the technology works.
2. If there is nobody willing to adopt a cluster using conf mgmt that they do not prefer.
We had an admin that set up an ELK cluster with cfengine. All of the other admins do not claim to understand it, and hesitate to maintain it, update it, make changes to it, and otherwise perform their job duties. One of the admins is partial to Chef, and the other wants to maintain the ELK cluster with Kubernetes. Only problem is neither has done so, and they have made little progress. I hope to see that change.
