31.8.1 step 11: Doesn't seem to work after reboot. I followed the steps and set a password for root. However, after rebooting the pxe boot machine, I was able to log in as root without password. step 12: Pxe machine seems to populate /etc with ${NFSROOTDIR}/conf/default/etc/. The documentation should use ${NFSROOTDIR}/conf/default/etc/ssh/sshd_config instead of ${NFSROOTDIR}/etc/ssh/sshd_config.
