How to run a program at boot on the Iomega Storcenter NAS

This tutorial uses unsupported features of the IOMEGA Storcenter ix4-200d. It worked for me but use it at your own risk! I undertand it works (but still isn't unsupported by IOMEGA) on the ix2 Storcenter as well.
Tutorial tested on IOMEGA Storcenter ix4-200d firmware 3.1.14.995
This post is extracted from a previous post (how to install crashplan on Iomega storcenter). I am planning more tutorials on the Iomega storcenter ix4 and wanted centralize this part in case it needs to evolve with future firmwares...


1. Enable SSH on the NAS
see my other post How to SSH into your Iomega Storcenter




2. Create a script that runs at boot
Iomega OS (EMC LifeLine) does not respect what is inside /etc/rcx.d/. If you have another brand of NAS, chances are that installing the script into /etc/rc2.d/ will result in the script running at boot...
If you already downloaded the scripts to have a command run at boot, you can just add the new command below the one you already have in /opt/init-opt.sh. Just make sure the commands all return immediately (or add a & at the end) so that the script does not get stuck before reaching the last command.

If that the first time you do this, download the scripts:

cd /opt/
wget http://dl.dropbox.com/u/50398581/Storcenter%20add%20on%20boot/editconfig.sh
chmod +x /opt/editconfig.sh
wget http://dl.dropbox.com/u/50398581/Storcenter%20add%20on%20boot/init-opt.sh
chmod +x /opt/init-opt.sh

Now we start editing the XML list of programs that will automatically be started. Run:

/opt/editconfig.sh

You will see lots of Groups. We are going to add one <program> to <group level="1">. We will add:

<program name="init-opt" path="/opt/init-opt.sh">
<sysoption restart="-1"/>
</program>

the scripts content for you reference:
/opt/editconfig.sh

#!/bin/sh
# edit the bootup config of the ix-2
# inspired by http://www.chrispont.co.uk/2010/10/allow-startup-daemons-on-storcenter-ix2-200-nas/
mknod -m0660 /dev/loop3 b 7 3
chown root.disk /dev/loop3
mkdir /tmp/apps
mount -o loop /boot/images/apps /tmp/apps
vi /tmp/apps/usr/local/cfg/sohoProcs.xml
sleep 1
umount /tmp/apps
rm /dev/loop3

/opt/init-opt.sh

#!/bin/sh
# modified from http://techmonks.net/installing-transmission-and-dnsmasq-on-a-nas/
rm /opt/init-opt.log
echo "Last bootup:" >> /opt/init-opt.log
date >> /opt/init-opt.log
#Add your command below
#/etc/init.d/xxxxxx start >> /opt/init-opt.log
while true; do
 sleep 1d
done

Then, you just need to edit editconfig.sh add the command(s) you wish to run after the

#/etc/init.d/xxxxxx start >> /opt/init-opt.log

line!
