That's how it is supposed to be.  Each run of `dump' dumps just one
filesystem.  fstab is only referenced in case you're specifying a
mounted resource (e.g. "/") instead of a raw device name (e.g.
"/dev/rsda1") to translate them.

Ah, well, i guess what has been confusing you: the -w and -W options.
Yep, they indeed read the entire fstab file, and compare it against
the dates of the last dumps taken via /etc/dumpdates.  But that's no
action, only informational output.  It's usually done nightly as part
of the /etc/daily cron job, and mailed to the system administrator, in
order to remind him if the dumps that are due.
