What I'm using right now:
Filesystem    Size     Used     Avail Capacity  Mounted on
/dev/wd0a     1.0G      38M      920M     3%    /
/dev/wd0e     2.0G      60M      1.8G     3%    /var
/dev/wd0g     9.8G     2.5G      6.9G    26%    /usr
/dev/wd0f     1.0G     8.0K      958M     0%    /tmp
/dev/wd0h      20G     3.5G       15G    18%    /home
/dev/wd0i      59G      56G      2.7G    95%    /media
/dev/wd0j      16G     2.3G       13G    14%    /misc
/dev/wd1a      19G      10G      7.5G    57%    /disk2

obviously, I should have partitioned more carefully. / and /var are barely
being touched, /tmp sure isn't, etc. This box has 384MB ram, I've used a mfs
/tmp, but found that it reduced performance instead of enhancing it, because
it sucked memory and caused swappage that otherwise would have happened
I believe IDE is junk as well, but I can't afford good SCSI at this point,
so I go with what I have.
