Well, the nodump flag is sort of inherited from the directory, since if 
the directory has the flag neither it nor anything in it will be dumped 
(assuming correct use of -h flag.  -h 0 ensuring *never* dumped).

Have you tried just setting the flag on the directories?  It works for me...

PS It's a slightly different problem if you do want the directory dumped 
but not any files in it; then you do have to resort to palaver like the 
above.  You could write a script or an alias that does the chflags and 
then runs the dump, though.
