The man page does not explain this adequately.  I'd like to see a
description of how dump(8) decides what date should be used as the basis
for the incremental dump (is it the date of the previous level 8 or
lower level dump as would be implied by "treated as level 9", or is it
the date of the previous level 9 or lower dump, as might or might not
be implied by "takes into account a previous level 9"?),  and how it
updates /etc/dumpdates (does it apend a new level 9 record, or does it
replace the previous level 9 record?).
