Tim, let me start by apologizing.  I did not intend to
lead you the wrong way down a one-way street.

I've specified multiple files on the command line
before but apparently they were on the same
filesystem.  I tried your example (although I'm
running dump-0.4b27-3) and I got the same error.  As I
re-RTFM it does appear that you can specify either
multiple files within a filesystem OR a single
filesystem (either mount point or device file.)

Sheepishly,
Brad.
