For those playing along at home, I believe the issue is that GNU tar
sees a different device number for the directories than what is listed
in the listed-incremental snapshot file, and thinks all of the
directories are new. I've asked Gene to make a few back-to-back runs of
the tar command under the same kernel to see if the subsequent runs
figure out that there's nothing to do, as expected.

Then it is a matter of figuring out why the device number changed -- I'm
thinking it is device-mapper, but will look closer tomorrow.
