[Icecast] Running Two Instances of Icecast

In order to test my SSL configuration, I thought it would be a good idea 
to run two instances of the Icecast server daemon--the one running our 
production environment, and a second one that no one would access but 
me. I copied the daemon file /usr/bin/icecast2 to icecast2-test, and did 
the same with the startup file in /etc/init.d after editing it to change 
the value of $DAEMON, $DESC and $CONFIGFILE to point to the copy 
mentioned above and the configuration containing the SSL stuff. I also 
copied the small webroot directory from /usr/share/icecast2 to 
/usr/share/icecast2-test. The configuration file is a copy of the 
production file with these important changes:

• The ssl and ssl-certificate lines were added in their appropriate stanzas.

• webroot was changed to point to the test location (see above).

• All port numbers were change from 800x to 700x.

• I meticulously checked all file ownerships and permissions, and to the 
best of my knowledge and ability, they're all correct.

However, when I try to start the second copy with:

./etc/init.d/icecast2-test start

I get the message that the daemon is "Detaching from the console...", 
and then it's just plain gone. 'ps -ef|grep icecast' shows only the 
production server process is running. There are no messages in 
/var/log/yslog, and access.log and error.log in the test webroot never 
get created, nor are there any messages in the production copies of 
these files. Something's happening to cause the process to abbend or 
otherwise exit prematurely, but I have no idea how to figure out what it is.

Just for kicks and grins, here's /etc/init.d/icecast2-test without the 
comment lines at the top:


test -x $DAEMON || exit 0

# Defaults

# Reads config file (will override defaults above)

if [ "$ENABLE" != "true" ]; then
     echo "$NAME daemon disabled - read $CONFIGDEFAULTFILE."
     exit 0

set -e

case "$1" in
     echo -n "Starting $DESC: "
     start-stop-daemon --start --quiet --chuid $USERID:$GROUPID \
         --exec $DAEMON -- -b -c $CONFIGFILE
     echo "$NAME."
     echo -n "Stopping $DESC: "
     # Send TERM after 5 seconds, wait at most 30 seconds.
     start-stop-daemon --stop --oknodo --retry TERM/5/0/30 --quiet 
--exec $DAEMON
     echo "$NAME."
     echo "Reloading $DESC configuration files."
     start-stop-daemon --stop --signal 1 --quiet --exec $DAEMON
     echo -n "Restarting $DESC: "
     # Send TERM after 5 seconds, wait at most 30 seconds.
     start-stop-daemon --stop --oknodo --retry TERM/5/0/30 --quiet 
--exec $DAEMON
     start-stop-daemon --start --quiet --chuid $USERID:$GROUPID \
         --exec $DAEMON -- -b -c $CONFIGFILE
     echo "$NAME."
     echo "Usage: $0 {start|stop|restart|reload|force-reload}" >&2
     exit 1

exit 0

I suspect I'm missing something very obvious. Any and all assistance 
greatly appreciated as always.
