The Community guide to GitHub Workflow has a short section on how to install etcd in K8s, by running hack/install-etcd.sh. But I'm running Fedora, which has what appears to be a perfectly respectable (and even newer) etcd package. Is there anything about the Fedora package that would be incompatible with the content installed by install-etcd.sh?
By default, it looks for pre-installed etcd, it just validates the version and after that, if it can't find the etcd, it will download the binary, so any way you can install the etcd from package manager but version should be 3.1.12 or newest (for now)
