Limitations of cp and mv?

[David J. MacKenzie]

In the next few years, I expect that most systems' cp and mv will
start picking up the ability to properly copy or move directory
hierarchies, because POSIX.2 will require them to do so.
cp -R (uppercase) will copy while preserving file types, and
mv (no special option needed -- I don't like that part) will move
entire directory trees across filesystems transparently.
