Start Application Automatically on Restart in Debootstrap Environment

By | March 26, 2013

If you install an application on a linux debian server, debian takes care of restarting the application when you restart the server. But when you start working on creating a new application on Debootstrap environment ( otherwise called as linux sandbox environment ) you can’t expect the same. On server restart, only applications installed outside the debootstrap environment gets started automatically not the applications installed inside the debootstrap ( chroot environment ). So how do we fix this? Well here is a work around.

So let’s me imagine that your debootstrap environment is located at /home/deboot/ and you want to start apache2 inside /home/deboot/. Now here are couple of script that can help you do that.

Create a script inside /etc/init.d/ and call it startapache

touch /etc/init.d/startapache

Give executable permissions to this file.

chmod +x /etc/init.d/startapache

Now, use the following script in /etc/init.d/startapache



count=`mount | grep /home/apmanager/apmanage/proc|wc -l`
if [ $count -eq 0 ]
if [ -d /home/deboot/proc ]
mount -t proc /proc /home/deboot/proc
echo ” ERROR: No proc directory.”

chroot ${SBOX_RT} ${DAEMON} > /dev/null

chroot ${AP_CHROOT} ${APACHE_DUP} > /dev/null

Now, inside the chroot environment,

chroot /home/deboot/

Create a file “/etc/init.d/”

Give executable permissions to this file.

chmod +x /etc/init.d/

Now use the following script inside “/etc/init.d/” to start apache.


/etc/init.d/apache2 start

In case you have multiple programs to be started inside chroot environment you can start them in the script /etc/init.d/

Now finally, to setup auto startup, go to /etc/init.d/ directory outside the sandbox and use the following command.

update-rc.d startapache defaults

The above command will add your script startapache to run when the system starts everytime.
