+[NOTE]
+.Lenny-Release
+================================================================================
+When installing lenny to a new mdraid, grml-debootstrap will use md metadata
+format version 0.90. This limits the device to a maximum size of 2TB, but has
+the advantage of grub-legacy actually being able to boot from it.
