run_kannel_box starts up a process (either bearerbox, webbox or smsbox) 
and make's sure that if it fails, it gets restartet.

Here's how I start kannel on my computer from /etc/rc.d/init.d/kannel. 
I let the processes run as user "kannel" at the same time:


RUN=/var/run/kannel
BIN=/usr/local/sbin
DELAY="1"
CONF="/etc/kannel.conf"

RUNBOX="${BIN}/run_kannel_box"
BEARERBOX="${BIN}/bearerbox"
SMSBOX="${BIN}/smsbox"
WAPBOX="${BIN}/wapbox"

PID_SMSBOX="$RUN/smsbox.pid"
PID_BEARERBOX="$RUN/bearerbox.pid"
PID_WAPBOX="$RUN/wapbox.pid"

echo "Starting bearerbox"
su -c "${RUNBOX} --pidfile ${PID_BEARERBOX} --min-delay ${DELAY} 
${BEARERBOX} ${CONF} &" kannel
sleep 10

echo "Starting smsbox"
su -c "${RUNBOX} --pidfile ${PID_SMSBOX} --min-delay ${DELAY} ${SMSBOX} 
${CONF} &" kannel
sleep 10

echo "Starting wapbox"
su -c "${RUNBOX} --pidfile ${PID_WAPBOX} --min-delay ${DELAY} ${WAPBOX} 
${CONF} &" kannel


if you start a kannel box process with run_kannel_box it will keep the 
process restarting if it fails.
Try it yourself and try to kill any of the box processes, and you will 
see they restart. pretty much like safe_mysqld in mysql.
to kill the processes, I kill the process of the PID file above which 
is the corresponding run_kannel_box process.
