Well Clonezilla is busy cloning the drive, but there is a problem here 
cloning to a USB attached drive.

One of the partitions is LVM and since this is a drive clone, including 
the partition table and boot sector, both LVMs (source and target) have 
the same name.  So Clonezilla switches to using DD with probably some 
bad parameters.  After running an hour, it has only copied 4Gb out of 
37Gb.  Note that the USB port is v1.1.

Now actually, I would have perfered renaming the LVM partition and its 
internal ext3 partitions.  I even had a naming convention laid out if I 
had do this via Install instead.
