You definitely do _not_ want to just run cp -r; that would destroy
all of your file ownership and permission settings.  cp -a is better,
since it preserves those, but I'm not sure how well it handles links
and device files.  Not well, I suspect.

This is a much saner option.  Personally, I mount the device directly
on /mnt, then use:

find . -xdev -print0 | cpio -pvdm0 /mnt

If the other version came from the HOWTO, I suppose it should work,
but it could have problems with filenames containing spaces or
certain other odd characters (prevented by the -print0 / -0).  The -d
on cpio ensures that leading directories will be created, which is
mostly just paranoia in this case, and -v is the ever-popular verbose
flag, because I like to see what it's doing.
