I've noticed this also, and see if on my NanoBSD Soekris box.  Given that 
the machine doesn't have a partition set up for dumping, and I don't want 
its dumps, I'd rather it didn't complain, as that will just cause 
unnecessary worry and questions.

This is similar to the devfs-at-shutdown error.  An error message that is 
a result of a harmless "problem" results in significant concern for 
end-users, which results in more bug reports, less happy users, etc.
