Customizing Ubuntu Part 2: Remastersys

Now that we have our customized Ubuntu system set up and up to date its time to install and begin the Remastersys setup. Before we tackle that though we are going to take care of the last little bit of house cleaning from the initial setup. First we will run (from terminal) "sudo apt-get autoremove" to clear out any old packages that are no longer needed and then we will disable auto login (as is default on the install) for our originally created user as the instructions on the Remastersys page are very clear to not use auto-login. After that we will remove old kernel files with Synaptic Package manger to free up space. Once we have Remastersys installed we'll clear out the Firefox cache just for good measure.

Installing was simple, I just followed the Synaptic Version of their install instructions on their Ubuntu page. The only difference was the packages didn't show up after just doing a reload in Synaptic, so I opened a terminal and ran "sudo apt-get update" and then found and installed Remastersys and Remastersys-gui from Synaptic.

Now that we have Remastersys installed, its time to open up the GUI version and start our ISO creation. You will find the program under the System Tools - Administration menu and will be asked for you password upon load. Once loaded, we will first choose the configure button to set up some basic options such as live user name and live CD name. After that we will choose the User settings option to copy all settings so as to be default for all users in our new customized ISO.

Next we will go back to the main Remastersys menu and Choose Distribution to start the creation of our ISO. Once you start this process, you will need to be patient and let the system be while Remastersys does its work. All told I think it may have taken about half hour or so to create my ISO that ended up at 1.1GB total.

Next step (and next blog entry) will be getting the ISO off the Virtual Machine and onto my main system for testing. Stay tuned.
