        And the swap partion does not get mounted (unless you are also
using it as a tmpfs).

        As an example, from my Intel-based 3.5 OBSD, I get the
following:

 ======================================================================
        (end of disklabel output. Note that partition 'b' is swap.)

# size offset fstype [fsize bsize cpg]
  a: 2097585 63 4.2BSD 2048 16384 328 # (Cyl. 0*- 2080)
  b: 2097648 2097648 swap # (Cyl. 2081 - 4161)
  c: 40132503 0 unused 0 0 # (Cyl. 0 - 39813*)
  d: 4194288 4195296 4.2BSD 2048 16384 328 # (Cyl. 4162 - 8322)
  e: 4194288 8389584 4.2BSD 2048 16384 328 # (Cyl. 8323 - 12483)
  f: 6291936 12583872 4.2BSD 2048 16384 328 # (Cyl. 12484 - 18725)
  g: 16777152 18875808 4.2BSD 2048 16384 328 # (Cyl. 18726 - 35369)
  h: 4477410 35652960 4.2BSD 2048 16384 328 # (Cyl. 35370 - 39811*)
 ======================================================================

        And here -- df shows the other partitions, but *not* swap,
because the kernel keeps it for its own use. (Note that of your list of
partitions, that one is the only one which does not start with a '/'.)
