Hello Mikal,
  I've used the double tar trick a few times and that works for most
files.  Strange things like sockets won't transfer over and there used
to be some problem with /tmp but that was a while ago.

Try to have most things not running so your number of open files is
down.  You can have some problems with open files.

cd /
tar cf - . | ( cd /newdir ; tar xf - )

I've used that a lot, especially when drives didn't used to be that
good.  Make the second tar xvf if you want to see what is going on.
