This is pretty easy. Just write a script for the class that echoes the host keys to the client's filesystem:

#! /bin/bash

error=0 ; trap "error=$((error|1))" ERR

set -x

echo "|1|lmK...yQ= ssh-rsa AAAAB3N.......== comment" >> $target/root/.ssh/known_hosts
echo "|1|9Gk...ZU= ssh-rsa AAAAB3N.......== comment" >> $target/root/.ssh/known_hosts

exit $error
