Opps, that's not totally true in retrospect - sometimes I left some 
unused space when I installed a distro so I could come back with 
FreeDOS.  However, I couldn't control the size of the physical 
partition that was created for LVM when I did the Fe7 install.  No 
matter what size I specified, it took the entire remaining free space.
