+This installer will install mysql-server on an Ubuntu machine.
+In addition to the normal installation done by apt-get, it will
+also configure the new MySQL server to store it's data files in
+a different location.  By default, this is /mnt but that can be
+configured in the [MySQL] section of the boto config file passed
+to the instance.
