Let's look at how startup scripts put in to /opt/etc/init.d/ directory are invoked.
1. /etc/init.d/rcS invokes /etc/init.d/rc.optware script. These are the last few lines in the rcS script.
/usr/local/bin/hdd_raid_syncspeed.sh
# Optware setup
[ -x /etc/init.d/rc.optware ] && /etc/init.d/rc.optware start
exit 0
2. Then /etc/init.d/rc.optware script mounts /opt partition and invokes /opt/etc/rc.optware script.
case "$1" in
start)
echo "Starting Optware."
if test -n "${REAL_OPT_DIR}"; then
if ! grep ' /opt ' /proc/mounts >/dev/null 2>&1 ; then
mkdir -p /opt
mount -o bind ${REAL_OPT_DIR} /opt
fi
fi
[ -x /opt/etc/rc.optware ] && /opt/etc/rc.optware
;;
reconfig)
3. This /opt/etc/rc.optware script simply executes scripts matches with S??* located in /opt/etc/init.d/ directory.
#!/bin/sh
# Start all init scripts in /opt/etc/init.d
# executing them in numerical order.
#
for i in /opt/etc/init.d/S??* ;do
# Ignore dangling symlinks (if any).
[ ! -f "$i" ] && continue
case "$i" in
*.sh)
# Source shell script for speed.
(
trap - INT QUIT TSTP
set start
. $i
)
So after some investigations I have found out that rcS script didn't execute it's last few lines. It seemed it exited just after executing /usr/local/bin/hdd_raid_syncspeed.sh line. The simple solution was to move this line to the bottom of the script so that the optware setup is executed first. Now the startup script added to the /opt/etc/rc.optware is started whenever the linkstation is rebooted. :)
The last few lines of rcS after the modification,
#/usr/local/bin/hdd_raid_syncspeed.sh
# Optware setup
[ -x /etc/init.d/rc.optware ] && /etc/init.d/rc.optware start
/usr/local/bin/hdd_raid_syncspeed.sh
exit 0
