Or (cd "$1"; find . -depth -print | cpio -pdl "$2"), according to the S5
"cpio" manual page.

It's not too hard to do (I did it a while ago, but don't have the sources
handy).  Both "cp -r" and "tar"/"cpio" have their uses.  "cp -r" is more
convenient, but back-to-back "tar"s and "cpio" will preserve more
information.  (Beware of symbolic links if you do a "cp -r", for instance;
"cp" doesn't know from symlinks.)
