This is true for all filesystems that have a "resize" command. Although I'm
not entirely sure of how to move a filesystem "forward" on a partition.

Example:

	|123DATA---|
	
Now we move the data forward with dd, this is the result:

	|123123123|

The data would have to be move forwards beginning at its end. I have no idea
how to do this. Any suggestions?
