Disklabel issues warning about unused sectors?

["Craig McLean" <craigels@home.com>]

Hello all.  I've installed OpenBSD for the first time and everything went
smoothly except for one detail which bothers me but didn't stop the install.

During the install after you have run fdisk and disklabel on your disks and
it is writing the information to the disk, it issues a warning saying there
are 16 unused sectors in the last cylinder.  As far as I can tell I've used
all the sectors on the disk.  If I just add 16 more sectors to my swap label
it tells me there aren't 16 more available, so I'm wondering what is going
on here.  I know this isn't a show stopper by any means, but it does bug me.

my partitions are as follows

     size           offset        fstype         [fsize        bsize
cpg]
a:  3107648     63           4.2BSD        1024       8192         16
#(Cyl. 0*- 3083*)
b:  65473        3107711   swap
#(Cyl. 3083*-3147)
c:  3173184     0             unused         0             0
#(Cyl. 0 - 3147)


Any help would be appreciated.
