User setting after first reboot?

[Thatoo]

Would it be possible to install without setting the user (name/password) at first and only ask for user settings after the first reboot? (maybe setting a default user at install if needed y the installation process and then after reboot, change name and password of this default user).
That would allow to make computers ready to be used in advance and make the (new) user have only one step to make : setting his own credential before using the computer.
