Bottlerocket without xvdb (only nvme ephemeral storage)

[awoimbee]

Hi,
It's possible to boot Bottlerocket with most (all?) data on the nvme disk:

    userData: outdent`
        [settings.bootstrap-commands.k8s-ephemeral-storage]
        commands = [
            ["apiclient", "ephemeral-storage", "init"],
            ["apiclient", "ephemeral-storage" ,"bind", "--dirs", "/var/lib/containerd", "/var/lib/kubelet", "/var/log/pods"]
        ]
        essential = true
        mode = "always"
      `,

But I still need to attach a ~2GiB disk to my nodes for bottlerocket to work. Is there a way to completely remove the xvdb disk and only use nvme storage ?

It's not currently possible, since the xvdb storage is used for other data such as host containers and logs in the system journal.
