Coming from a user with an oar about the size of a toothpick, I would be 
far more concerned with the minimum size, make 'em work to find it if its 
a worthwhile target.

Some random 3 or 4 word combo will be at least 15 chars, so thats the 
minimum, and 31 chars max will take, its been said, till the universe 
runs down.  Advances in computer tech might cut that to 10 years in 
another 20 years time though.

Hard and fast rules s/b in the eye of the beerholder so they should be 
optional. 40 chars would be ok for the ups backing up the control 
circuitry of a nuclear power plant, or one of the generating stations 
just west of Farmington NM. Either of those maliciously shut down would 
put 20 million in the dark.

OTOH, mine isn't a big enough target to make it worhwhile so I don't 
think mine even needs a separate passwd. The guy in charge, with sudo 
rights, should be able to set that, or not, at install time.

Take care and stay well everybody.

Cheers, Gene Heskett.
