=====Initial Steps=====
These steps are needed before attempting asterisk installation:
  * Set your Odroid up with a static IP address
  * set the ntpd to start and update the time
  * Set a Super User Password
  * Make a normal user
  * Make sure you can SSH into the Pi.

Now log in as the super user (root) and stay in the root home folder (/root/). Everything we are doing here is done in bash.  I suggest SSHing into it so you can copy and paste commands.

====Stopping the GUI====
run the following command to stop the Odroid from booting into the GUI and hogging resources:
<code>ln -sf /usr/lib/systemd/system/runlevel3.target /etc/systemd/system/default.target</code>

====Expanding the file system====
Run fdisk
<code>fdisk /dev/mmcblk0</code>
Press the following commands:
  * p(see starting block of p3, e.g. 1041016)
  * d (delete)
  * 3 (partition 3)
  * n (new)
  * p (primary)
  * 3 (partition 3)
  * 1041016 (starting block)
  * <enter> (it will take ending block as end partition, so you have entire space)
  * w (write partitions)

Upon successful editing of the partition resize the image to the partition:
<code>resize2fs /dev/mmcblk0p3</code>

Check the file system has been expanded:
<code>df -h</code>
