+		  The new ext4 file system is available in Fedora 9 as a nearly feature complete preview. Testers are encouraged to review the documentation and try implementations of ext4. When finally integrated, users should experience no problems with the new file system, and should find it bigger, better, and faster.

+	  <para>
+		  While an ext3 file system can be mounted as ext4, an ext3 to ext4 conversion tool is planned that converts existing ext3 on-disk format to ext4. For more information about this feature:
