oh ok,I'm just a noob so I thought the opposite of a "passwordless sudo"  was 
one with a password lol

Also what does Joanna mean by this statement on that page?  " At the same time 
allowing for easy user-to-root escalation in a VM is simply convenient for 
users, especially for update installation."

If you are talking about some other form of authentication (sorry I have a hard 
time following your convo with Uman, 0 timeout period for sudo?) then what 
would make it inconvenient for users? We already have to hit y or n to update 
templates.

I still think its more about usability then whats trivial to bypass. And in 
that case its based on threat model. Sure security is difficult, but its more 
about controlling yourself then your machine, imo.

But I know you are genius Chris and if there is some method to authenticate to 
sudo without a password that would not be cumbersome for users I would be for 
that option.
