This guide shows how you can create a Live-CD from your Ubuntu Gutsy Gibbon or Linux Mint 4.0 system with a tool called remastersys. Remastersys is available in the Linux Mint romeo repository. You can customize your Ubuntu/Linux Mint system and then let remastersys create an iso image of it which you can then burn onto a CD/DVD.

Remastersys is a tool that can be used to do 2 things with an existing Klikit or Ubuntu or derivative installation.It can make a full system backup including personal data to a live cd or dvd that you can use anywhere and install. It can make a distributable copy you can share with friends. This will not have any of your personal user data in it.

The attempt to copy the entire disk image using cp may omit the final block if it is an unexpected length; dd will always complete the copy if possible.
We can use the dd command to create an ISO disk image of a CD or DVD.

Previously some there was some problem for remastering Ubuntu 9.10 (Karmic koala). Karmic Koala is using Grub 2, remastersys is designed for grub 1. Now Remastersys is redesigned for ubuntu 9.10 with grub 2 and it is working. you need Remastersys version 2.0.13-1 or higher.
All other options are just like previous versions.

I recently had a project that needed to do a whole lot of number crunching, and then create a PDF to present those numbers and a line chart as well. This presented two problems for me - how to create a PDF from code, and how to create a chart for use within that PDF. I can say that I have had some success and wish to share with you the process.

The two tools I use for creating new vm’s with libvirt are virt-install and vmbuilder. I use virt-install when I will be installing an OS from installable media or using an existing disk image, and vmbuilder when I need to create JeOS based vm’s.

After countless hours of configuring, tweaking, installing new applications onto your Ubuntu system, the last thing that you want to do is to reformat and start everything all over again. Remastersys is here to save you all this trouble.

SystemImager lets you create images of your Linux installations. To do so, you need an image server (should have enough disk space to store your images) and a so-called golden client (i.e., the system of which you want to make an image).

Now a days, when one installs Linux on ones machine, in more cases than one, there is a trend to create a logical volume and create the file system on this volume rather than creating the file system in individual partitions.
