Is Cracklib really required in the OS image?

[Gary C Martin]

Out of curiosity I was just doing some visual treemapping of an XO  
build image, and noticed an ~8Mb file containing dictionary crack-able  
passwords. I take it this is for legitimate OS protection to stop  
users choosing weak passwords, but with the goal of not using  
passwords, and the this file is mainly English language, it seems a  
bit of a waste of 9Mb.

Sorry if this has been covered before, probably has some critical  
dependancy.

P.S. Don't know enough about the build process to investigate this  
kind of stuff myself.
