Boot to single user mode "mount -u /" and change the password
Jeff Berliner [jeff_at_popmail.med.nyu.edu]
easy thing to do is pull the drive from the machine, mount it on

(Solution used with additional note: "In fact , a security concern
is if someone hits the halt button , they can then boot into single user

( using " boot -fl s " at the console )".)
