    Here is my STARTNOS script:


#!/bin/bash
#
# /jnos/startnos
#
logger "JNOS startnos script started"
cd /jnos
rm -f /jnos/spool/mqueue/*.lck 2> /dev/null
rm -f /jnos/spool/mail/*.lck 2> /dev/null
#
export TZ=EST5EDT
export TERM=linux
#
# Actually start jnos 
logger "JNOS is being started"
exec screen -d -m  ./jnos -d /jnos -f /jnos/nos.cfg 2>&1
#
logger "JNOS has exited"
#
# 
# --- end ---
#
