heheh...one of the wonderful things about *x is that we can do it so
many ways.  my favorite is:
cd /usr
find . -print | cpio -dump /mnt/<yourmountpoint>

if there are things you don't want to move, say huge .iso files, you can
filter them out with grep before cpio sees them.

i'd settled on cpio years ago because it's a byte copy, as opposed to a
block copy like tar.  the difference can make a huge difference if you
are moving tons of small files.  less difference if you are moving only
very large files.
