Raphael, we have observed that the user's public key gets installed by curtin such that user can ssh into the installation environment. To recreate, you would deploy a node from MAAS, then try to SSH into system once system is pingable and until it lets you in; ssh returns connection refused before finally succeeding. You can then check mounted filesystems and cloud init logs to ensure you are in the installation environment. Lastly, keep the SSH session opened in order to observe it getting killed as a result of system initiating post-install reboot.
