I need an alternative software of Remastersys since it's not working in my system (Ubuntu 12.04.)

I want software just like remastersys. I don't want to install any new packages, I just want a piece of software that makes an ISO of my current system without any added packages.

Relinux is the best software to use instead of Remastersys.
Here is a great tutorial how to use.
Download the latest version from launchpad

The image created with Relinux can under no circumstances be greater than 4 GB, this is often the bottleneck to use Relinux. – i08in Mar 17 '14 at 11:43

Ubuntu-builder needs to download packages again and you'll not use the already founded ones in your system so its a bad choice of Remastersys but its great tool (which i tried before) to build from zero – user61928 Oct 12 '12 at 14:38

System Imager is a fork of Remastersys. The latter is not being developed anymore.

From System Imager's website:

System Imager is a tool that images your running system and allows you to make a image of your running machine and install it on another. System Imager is based on the work of Remastersys.

It has been released under the GNU GPLv2 and the source code is available from the developers in

Distroshare Ubuntu Imager is a new script that I developed: . It is based on this guide:, but includes some bug fixes and extras.

System Imager turned into Black Lab Image Creator, which is no longer free. Re-linux has not been maintained for a while and is no longer under development.
