mount point cluestick please (newbie question)

[James Zuelow <jfzuelow_(_at_)_alaska_(_dot_)_net>]

Hello - I've been running Linux for a not quite a year, and have recently
set up two OpenBSD systems (one 2.8 & one 2.9).  The 2.8 box is a P100
with a very small drive, so I didn't put X on it (it will eventually
become my firewall when I learn more about pf).

When I installed the 2.9 system, I created a partition for X.  Here's
my df -h output (as root):

Filesystem    Size   Used  Avail Capacity  Mounted on
/dev/sd0a     496M    27M   445M     6%    /
/dev/sd0d     248M   2.0K   236M     0%    /tmp
/dev/sd0e     248M    23M   212M    10%    /var
/dev/sd0f     124M   1.0K   117M     0%    /usr/X11R6
/dev/sd0g     496M   373M    99M    79%    /usr
/dev/sd0h     496M   6.6M   465M     1%    /home
/dev/cd0a     647M   647M     0B   100%    /mnt/cdrom

Since I have X up and running with KDE, I was sort of surprised to see
that the partition is at 0% capacity.  Also, I'm not sure what to make
of the 117M available out of a 124M partition being 0% used.

Just to be sure that I named the partition correctly, I did an ls -l
of /usr/X11R6, and got exactly what I expected:

total 11
-r--r--r--  1 root  wheel  4051 Apr 23 13:50 README
drwxr-xr-x  2 root  wheel  3072 Jun 27 19:46 bin
drwxr-xr-x  6 root  wheel   512 Jun 22 12:55 include
drwxr-xr-x  4 root  wheel  1536 Jun 22 12:57 lib
drwxr-xr-x  7 root  wheel   512 Apr 24 10:01 man

All of the directories are populated.  A du /usr/X11R6 (again as root)
also shows the directories and their contents as being present. It's
quite long, so I haven't posted it but can on request.

>From my Linux experience, something isn't right.  /dev/sd0f should
have quite a bit of space used up for the X install, and a cursory
inspection of /usr (/dev/sd0g) makes me think that at least some of
the 340MB shown as used should be on /dev/sd0f instead.  Instead, it
looks as if /dev/sd0f only has the tables of contents for the
directories actually in /usr/X11R6, while all of the subdirectories
and their contents are on the /dev/sd0g partition.

I've looked through the man pages, etc. but I must be missing
something.  All of these partitions were created during the initial
install - nothing added later or modified in any way.

Anyone have a cluestick for a BSD newbie as to why (apparently)
nothing is being written to /dev/sd0f?
