This problem and others can be solved by telling GNU-tar about the file
system.  There is no reason a system utility shouldn't be aware of the
system layout.

How many CPU years are going to be wasted LZW'ing all those sparce blocks
when a little file system knowelege would have saved us all that grief?
Write the code once and be done with it.
