If I want to build a small cluster with three controlplane nodes and one dedicated etcd node, in what order should I build the nodes?
The Managing Server Roles page
Managing Server Roles | RKE2 says I should “deploy a config with all the control-plane components disabled.” Cool.
It also says, ‘a dedicated ‘control-plane’ node cannot be the first server in the cluster; there must be an existing node with the etcd role before joining dedicated ‘control-plane’ nodes.’ OK.
I have one controlplane node with roles ‘control-plane,etcd,master’ and one node I’d like to use as a dedicated etcd node. Do I need a second controlplane node running before I try to stand up that etcd-only node?

Thanks.
