Certain files are not displayed in rancid.  Take a look at  ShowFlash
and DirSlotN in rancid to see which files are not displayed.  eg
  # Filter dhcp database
  next if (/dhcp_[^. ]*\.txt/);

I added a 'redacted' variable - eg:
        if (/dhcp[-_]database\s*$/)  {                  # -LR- ignore
dhcp database changes
            $redacted = 1;                              # -LR-
remember that a file has not been displayed
            next;                                       # -LR-
        }                                               # -LR-

and then suppress the bytes free line if files have not been displayed:
        if (/.*\(\d+ bytes (free|used)\)/) {            # -LR- want to
show bytes free?
           if ($redacted) { next; }                     # -LR-   not
when there are files that haven't been shown
        }                                               # -LR-
