Looking into it, in Karmic and before, tftpd was started with: OPTIONS="-l -s /var/lib/tftpboot" start-stop-daemon --start --quiet --oknodo --exec $DAEMON -- $OPTIONS
And now it runs with:
TFTP_OPTIONS="" start-stop-daemon --start --quiet --oknodo --exec ${DAEMON} -- --listen --user ${TFTP_USERNAME} --address ${TFTP_ADDRESS} ${TFTP_OPTIONS} ${TFTP_DIRECTORY}
So it lacks the "-s" (or "--secure") by default.
