because df shows mounted disks, and fstab what to mount. neither of them affect
b (usually swap) or c (as per Olivier below).

you can see b by using the right command, for example, swapinfo:

$ swapinfo
Device          1K-blocks     Used    Avail Capacity
/dev/ad0s1b.eli   4194304        0  4194304     0%


( mine has .eli @ the end because it's an encrypted swap device).

indeed :) gstat shows them anyway because they are part of the GEOM subsys - u
just need the right tool  to see them.
