-#- defaults methods for adjusting start and end for partitions, these

-#- furthermore on the interface, choosing 1Mb more is possible that
-#- will go again beyond the normal cylinders boundaries, which may
-#- cause overlaping partitions again :-(
-#- until all the code in diskdrake is not cleaned up perfectly, rounding
-#- down for the end is necessary.

+#- is allowed for starting a partition after a cylinder boundarie.
