the "to" device can be the same or larger.  it makes the larger device look
the same size as the original, however, so you can't simply use the
additional space for anything.

so far as i know, df in both the *bsd and GNU varieties just reports a 
list of the filesystems mounted and their size, usage, and mount points.
in my mind df stands for "disk free" (space) and so far as i know no 
version supports arguments that make it work like dd.
