Using option --exclude SHELL_PATTERN will work.  I backup from /
(root) downwards excluding /proc, /dev, /sys, etc. file system content
like this:
    rdiff-backup --exclude /proc/** --exclude /dev/** --exclude
/sys/** ... / $BACKUPDEST

--exclude /proc/** excludes everything below the /proc directory, but
the directory itself is backup up.  Exactly what I want so that on
restore an empty directory is created as the mount point.

Alternatively the --exclude-if-present option is documented in the
manual page as another option that would meet you needs.  I haven't
tried it myself but something like this would appear to work.  (The
name .no-rdiff-backup is not special.  It just has meaning to us
    cd /mnt/nfs25t
    touch .no-rdiff-backup
    rdiff-backup --exclude-if-present .no-rdiff-backup ...
