 For flatcar-linux we can follow the advice on the sig-storage-local-static-provisioner website: Mount formatted block storage on `/mnt/local-disks/<UUID>`. The UUID will be used to make sure mixing block devices will fail and not expose data to the wrong host. For flatcar-linux we can follow the advice on the sig-storage-local-static-provisioner website: Mount formatted block storage on `/mnt/local-disks/<UUID>`.
