Since I finally got this thing settled with partition sizes, that's 
pretty complicated.  I have root, /boot, /home, portage and a data 
partition for misc. junk.  I doubt it will change any in the near future.

I did read up on it one time a while back.  It's neat when you have to 
add drives and resize things but still a bit much for a little desktop.
