I have started a thread on this topic on the Linux Internationals Forum here : --

How to 'copy2ram' for faster LiveCD sessions


Useful links : --



 which discusses how to customise a LiveCD to include boot2RAM



This article aims to document the process of creating a customized Ubuntu that loads an image from the hard disk to RAM, then boots an entire Ubuntu session out of RAM.
It is intended for intermediate to advanced Ubuntu users who are familiar with the shell, and may have limited experience customizing the livecd (LiveCDCustomization) and shell scripting.
We will customize a LiveCD and copy it to the hard drive, and make a few modifications to bootup scripts so that it copies to RAM via our good friend tmpfs.


This information should be useful when installing the Live Session to a USB device.



 which discusses how to customise a LiveCD ISO to add/remove applications, make it copy2RAM if it doesn't already, and remake the ISO with your customisations included.


Comment 36 for bug 25496

 which discusses a work-around to use when copy2RAM in a LiveCD is not working properly.


The aim of this mini-project is to test whether it is possible to boot a LiveCD with copy2RAM, using a boot parameter from the command line, when this is not included normally in the LiveCD itself.


Steps to a solution : --


1) Try booting the latest Ubuntu 2010.04 and interrupting the booting process.


2) Develop the cheet-code to copy2RAM.


3) Test the boot process.


4) Try with another distro, such as Pardus 2009.2


5) Write up the procedure.
