This installer assumes that you want the volume formatted as an XFS file system. To drive this installer, you need the following section in the boto config passed to the new instance. You also need to install dateutil by listing python-dateutil in the list of packages to be installed in the Pyami seciont of your boto config file. If there is already a device mounted at the specified mount point, the installer assumes that it is the ephemeral drive and unmounts it, remounts it as /tmp and chmods it to 777.
