OK, but I believe it is best to avoid this at all in incrementals.

I am not convinced that there is a need to have a single incremental
that spawn more than one filesystem. Star did have thousands of successful
real life incremental dump/restore cycles cince May 2005 (after the last
bug was fixed) with man gigabytes of data for each incremental. I believe the
idea of "make if simple and correct" was a good decision.
