OK.  Excellent justification for LVM.  So far I have not done VMs, but I 
have been thinking heavily about it.  But not HOW to do it. Seems like I 
probably should if I want to set up my drive now for VMs soon.

And well, my main system is a laptop, though only 12".  Just the right 
size to use in flight.
