how can I force “delete before replace” behavior on a given resource (e.g, subnets which can’t have the same CIDR)? Pulumi can clearly do this automatically for certain resource types, I somehow am just missing the flag to make it happen manually in the docs 🙂 edit: nevermind, I think it would work automatically in the common case. I ran into this because I renamed it, in which case “delete before create” wouldn’t have helped. Manually deleting the old one in the console fixed it.

Yeah - we don't support requesting this on a resource-level basis yet - we will soon: https://github.com/pulumi/pulumi/issues/1620
