>Description:
I think this speaks for itself:

slab# df /
Filesystem  1K-blocks    Used  Avail Capacity  Mounted on
/dev/ad0s1a   1795182 1682686 -31118   102%    /
slab# df -h /
Filesystem    Size   Used  Avail Capacity  Mounted on
/dev/ad0s1a   1.7G   1.6G -30.4M   102%    /
slab# df -m /
Filesystem  1M-blocks Used             Avail Capacity  Mounted on
/dev/ad0s1a      1753 1643 36028797018963937   102%    /


>How-To-Repeat:

Gobble up space until you end up in root-reserved space, then run df -m
