Changing the Kali Linux 2.0 Default Password

I could not find this documented. There is a script in /lib/live/config called 0031-root-password. It invokes the usermod command:

usermod -p ‘X014elvznJq7E’ root

which needs to be commented out and the filesystem compressed using mksquashfs. There is likely another way as well, but I have not searched for it.
