In general, you _rarely_ want to use the h option.
You don't want to dereference symlinks, device nodes or any other
special files, you want to tar to copy them as symlinks, device nodes,
etc...

That should be the default in all versions I've used -- BSD, SysV, GNU,
POSIX-2001 "pax", star, etc...

Also, you _rarely_ want to use the P option.
When restoring, you want to be able to restore relative paths under
whatever "scratch" directory, and not overwrite things from root which
storing the leading / does.
