I believe this comes from /etc/init.d/bind9.
Change this init script to avoid playing with rndc.

comment the reload part:
#    reload|force-reload)
#        log_daemon_msg "Reloading domain name service..." "bind9"
#        if ! check_network; then
#            log_action_msg "no networks configured"
#            log_end_msg 1
#        fi
#        /usr/sbin/rndc reload >/dev/null && log_end_msg 0 || log_end_msg 1
#    ;;

switch reload to restart:

Yes, it is slower. Yes, it interrupts the bind service for a short time.
So what. Boot error is gone.
