Wouldn't it look like

Filesystem          1K-blocks      Used     Avail Capacity  Mounted on
/dev/mirror/gm0d      4058062   -377792   4111210   110%    /tmp
/dev/mirror/gm0e     15231278   -113942  14126718   101%    /var

then? I always assumed that a disk occupation > 100% would go into
this reserved area, which would turn the Capacity field to be more
than 100%, and not less than 0%? This is the case when I have more
data on a UFS partition than it "is allowed to"...
