That's a good/interesting idea.  One suggestion; if you do this, make
sure you check to see if you are running on batteries; if you are,
it's likely that you might be in a situation such as a laptop on an
airplane and the airline attendant has just told you to shut down all
electronics in preparation for landing --- or the laptop has just
reported that you only have 3% battery life left, and please shut down

Sometimes doing a 3-5 minute FSCK run at shutdown isn't always the
right thing....
