logging in without a user and all the security issues around nfs

I am afraid that letting devices that boot over the network log in to the server without any authentication, does automatically imply security issues.
Perhaps with Pi 4 it would theoretically be possible to store security tokens in the EEPROM and use those, but that is not functionality supported out-of-the-box by Piserver.

(Naturally storing authentication tokens on a SD card is possible as well, like Berryboot does to store the iSCSI password to connect to network storage.
But then you will not have a fully network booting environment).
