Disable OS X auto-login after Filevault 2 unlock

Interesting nugget from the munki-dev list, a description of how to stop the auto-login that occurs after FileVault 2 unlock (I haven't tested this yet). You essentially disable the credential forwarding from the disk unlock window to the login window.
Edit /etc/authorization
Find the "system.login.console" array.
Find the "mechanisms" array within this.
Remove the line "builtin:forward-login,privileged".
Save and reboot.

You have a command line way of doing this so I script it?

Mavericks changed how this worked fairly significantly, see here.
