Making your own custom Linux distro image/live cd.
Many people would like to make a customised version of Ubuntu or other Linux distro. It is possible and not that hard, however, you’ll have to do it yourself.
Posting your ideas isn’t going to get anything done; you will have to make the effort to make them happen. That being said, here are some guides and sites on making various custom images. Each link will bring you to somewhere you can get information. It is up to you to decide which one to use.
* Custom Ubuntu Live CD
* Remastersys (Works with Ubuntu and variants)
* Reconstructor
* Revisor
* Create Your Own Fedora Distribution with Revisor short guide
* Custom Nimblex
* Larch
* Live Helper (Debian only!)
Thanks again to LaRoza & others on the Ubuntu forums.
