That method simply copies the live cd to your drive. It remains read only so you can't update any packages. I use a setup like this on my file server as it is pretty crash and hacker proof. Pretty much no matter what happens, the OS is protected and a reboot will get everything working again.
On the down side if you want to use an updated package you have to install it every time you boot. Installing as a hard drive allows you the freedom of a normal install with slightly higher wear. In practice, if the computer is used just to control a machine the drive will last virtually forever. If you use it as a desktop machine as well, the drive life will be reduced but even then it will take a long time to wear out. Manufacturer's wear figures tend to be very conservative. I often use Hitachi microcontrollers that are rated at 100 rewrites. Some of my development boards have been programmed many hundreds of times and I have never had a failure.
