I have gotten several replies to my query as to where over 10 Mbytes of
disk space have disappeared to.  Most related to a process creating a
file, rm the file, but the process still fills the area.  Others related
to similar 'hidden' files.  One wondered if I tried it as root?  Hmmmm . .
. of course . . . 

Anyway, I brought down the system, brought up the miniroot off of tape and
fsck'ed the partition . . . I did find @4 Mbytes this way.

Under the miniroot, the root partition, I mounted the root partition of
this disk as /a and the /usr partition as /d (so I could use du).  From
df:

        Filesystem            kbytes    used   avail capacity  Mounted on
        /dev/xy0a              30191   21692    5479    80%    /a
        /dev/xy0d             132904  115730    3883    97%    /d

BUT, when I did a du on these 2 partitions, I get a WILDLY different
answer (from the last line):

        13201   /a
        115730  /d

Hmmmm . . . the /d 'du' matches the 'df' estimation, but the /a 'du' is
still almost 8 Mbytes off!!!!!

Now, mind you this was NOT on a working disk, I had installed the miniroot
and was mounting these partitions (I was NOT using the root partition off
of the disk).  I thought I might have screwed up the partitioning (I
DIDN'T reformat when I just moved up from 4.0 to 4.1.1, just had
suninstall do it's newfs thing), but wouldn't a screwed up partition shown
up in 4.0???:

        Current partition table (original xy0):
            partition a - starting cyl      0, # blocks    64320 (64/0/0)
            partition b - starting cyl     64, # blocks   196980 (196/0/0)
            partition c - starting cyl      0, # blocks  1743675 (1735/0/0)
            partition d - starting cyl    260, # blocks   283410 (282/0/0)
            partition e - starting cyl    542, # blocks    37185 (37/0/0)
            partition f - starting cyl    579, # blocks   423105 (421/0/0)
            partition g - starting cyl   1000, # blocks   510540 (508/0/0)
            partition h - starting cyl   1508, # blocks   228135 (227/0/0)

I'm baffled . . . Any help?  I never had this problem with OS 4.0, just
since I upgraded to OS 4.1.1 . . .  Thanks . . .
