QNAP append more hostname to /etc/hosts

I found a very useful reference for updating the /etc/hosts after reboot. With the following reference, the /etc/hosts was overwritten by another process after reboot.

With the following script, I could automatic reboot /opt/sbin/asterisk and append hostnames to /etc/hosts after reboot.
  1. #!/bin/sh

  3. {
  4.   ###
  5.   # Section 1: Changes that can be made immediately.
  6.   ###

  8. /opt/sbin/asterisk

  10.   ###
  11.   # Section 2: Wait for it...
  12.   ###

  14.   date; echo "Waiting for boot process to complete."
  15.   while [ ! -f /tmp/.boot_done ]; do
  16.     sleep 1
  17.   done
  18.   date; echo "Boot process completed, making custom changes."

  20.   ###
  21.   # Section 3: Changes after the boot processes have finished.
  22.   ###

  24.   cat >>/etc/hosts <<EOD
  25. 203.80.89.135   s2hkbntel.net s21.hkbntel.net
  26. EOD

  28. #  crontab /xyz/home/userx/crontab -u userx
  29. #  date; echo "autorun_subproc ended."
  30. } >/tmp/autorun_subproc.out 2>/tmp/autorun_subproc.err &
