the password is on the root partition (in /etc/cipe, which by definition 
be in the root partition). if you're gonna encrypt the root partition, and 
lend out the laptop, you need to release the password for the root partition,
otherwise you might as well not lend out the laptop in the first place.

  If each of us have one object, and we exchange them,
     then each of us still has one object.
  If each of us have one idea,   and we exchange them,
     then each of us now has two ideas.
