I question this only because, if done from a CD bootable OS, I would 
think it would overwrite all the data on the mounted partition with all 
zeros, which is not what I want.  And if done from the live running OS, it 
may cause instability of the filesystem when complete by likely writing 
over existing files.

Or am I missing something?

I only want to zero out the unused space to help dd go faster and produce 
smaller files when I image the partition.
