Unfortunately, not one that preserves the holes exactly the way they
existed in the original file. See
http://reality.sgi.com/zwicky_neu/testdump.doc.html for a good discussion
of the problems of copying files with holes via the userland interface
to the file system. If all you care about is the space, you could write
a version of cp that compressed all zeroed blocks into holes.
