Copying a file system w/ tar - symbolic links not copied right - More info

[Don O'Neil]

Hi all...

Ok... More info for the puzzle.....

 I'm trying to move a file system from one disk to another, and when I do
this:

tar cf - /source/* | ( cd /destination && tar xfv - )

It copies all the files, but the symbolic links are copied as files of 0
length, rather than re-established as links.

BUT

When I just:

tar -cf file.tar /source/*

And then:

tar -xf file.tar

Then the symbolic links are made correctly.... Any reason why this should
work and not the piped version for 'all in one' copying?
