Password Recovery

[Tearlach]

Couple of newbie questions: (1) Assuming one has created additional admin users and disabled root, will the console password recovery process (option 3: reset root user password) still work?  In other words, will the console password recovery process not only allow one to reset the root user password but also reenable a disabled root user account?  (2) Where does one look to verify whether a particular installation used ZFS or UFS filesystem?  I could have sworn it used to be displayed on the Lobby Dashboard . . .

Thanks
