Making a casper persistent Ubuntu 7.10 (Gutsy Gibbon): With the coming release of Ubuntu 7.10 code named "Gutsy Gibbon", most of the portable linux community is likely going to want to run Ubuntu Gutsy from CD, USB or emulated using Qemu. So it only makes sense that, at the very least, we should be able to save and restore settings changes via a persistent partition or img (image).
Making a casper persistent Ubuntu 7.04 (Feisty Fawn): Since the initial release of Ubuntu 7.04, much of the portable linux community has been eager to run Ubuntu 7.04 persistently from a USB device or emulated using Qemu. It only makes sense that we should be able to save and restore settings changes via a persistent partition or img (image). In the following tutorial, we are simply re-enabling the old casper system.
This tutorial explains how to fix the Ubuntu Boot to Ram or "toram" feature that was broken in Ubuntu 7.04. Boot to Ram will enable a user to copy the entire Ubuntu live environment to system ram and run the Ubuntu Operating System entirely from there. You can then remove the CD or USB device and continue to do your work from system memory. BootToRam is also commonly referred to as CopyToRam.
Along with the final release of Ubuntu 8.04 came a bug which broke the persistence feature, ultimately dropping the user to a shell when booting with the persistent option. As it turns out, the problem lies with permissions being set to 755 for the cow device (strangely enough the prereleases did not have this problem). In the following tutorial, I will show you how to quickly fix the problem. This is the same process we used to create the custom initrd.gz file that is distributed with our Ubuntu, Kubuntu and Xubuntu 8.04 Hardy Heron related USB flash drive installation tutorials.
Setting the default root password: Some Live Linux distributions are created without a root password by default (the root account is inactive). This is particularly true with Debian based distributions like Ubuntu. Setting a root password enables us to access some essential tools such as the synaptic installer. In most cases, having no root password is fine when your running from a Live CD and don't need to do administration tasks, make changes or install additional packages. But for those of us who do want to make administrative changes and save them back to a USB device or local storage device on for example a properly created "casper-rw" partition. Setting the root password might then be necessary.
