i want to create from an already installed linux distribution (ubuntu, fedora, debian, etc) a custom installable version of it, to make myself more clear, i want to install in several computers a custom linux distribution, with the software i wanna use and the configuration i choose. It's tiresome to install the same software and make the same configuration over and over again, so i wanna know a way to create from an already installed and configured linux distribution an installable version of it to use it in any computer.
I will appreaciate any help you can give me
