chef node attribute, wtf?

  ruby_block "Create or attach LVM volume out of #{raid_device}" do
    block do
      BlockDevice.create_lvm(raid_device, options)
      node.set[:ebs][:devicetomount] = node[:ebs][:lvm_device]
      node.save unless Chef::Config[:solo]
    end
    only_if { options[:uselvm] }
    action :create
  end

  mount options[:mount_point] do
    fstype options[:fstype]
    device node[:ebs][:devicetomount]
    options "noatime"
    not_if do
      File.read('/etc/mtab').split("\n").any?{|line| line.match(" #{options[:mount_point]} ")}
    end
  end
