Differently for each distribution.

hostfiles are the same, network configuration including hostname can be done by dhcp.

This is not mandated by diskless configuration, you may choose to share / ro between clients and have a rw copy of /var for each client or you may choose to have an entire fs tree for each client.
Another option might be to use fuse although I don't have much experience of that myself, it's basically the same but each client would have a copy-on-write version of /var and /etc to allow them to write to files in these directories.
