No problem: just set a password with passwd for either root or
olpc. You could even create new users if you want to.
Only, be careful when running the olpc-update script: it will
reset all your changes to the OS.

Sure. To me to. You and me are clearly not the kind of
audience for which we had to disable the passwords. Thus,
you're free to re-enable them.

You seem to be under the impression that we compiled-out
the ability to set passwords in the system. That is not
What we're actually doing is just to disable them in the
default installation so that malicious activities cannot
login as root or olpc and basically own the system.

Here at MIT the XOs have public, globally accessible IPs, and
the logs are full of ssh connections trying random passwords.
In deployments, we're using primarily IPv6 and I was under the
impression we will not need NAT gateways.
