Copying Sparse files?

[Reg Clemens]

I need to copy a sparse file from one partition to another.
Actually, I need to copy it to an intermediate file,  move that file to 
another machine,
repartition, and then bring the sparse file back.

The sparse copy is not that hard to write,- someone must have one, but my 
scanning
of Fedora  with 'man -k sparse' and 'man -k copy' don't find anything.

Standard copy routines (and scp and tar) are not an option, as they will 
expand the
file by a factor of more than 1000 from a little over 1MB to over 1GB.  Ive 
thought
of dump/restore (which doesnt seem to exist for Linux), and rdist, but both 
seem
more complicated to setup than this problem deserves).

Any thoughts?
Otherwise Ill have to write something tonight.
