Tool to save customized live distro?
I need to save a customized live distro that I use to boot off a USB keydrive, where "customized" means that I added/removed applications and drivers, changed settings like the keyboard layout, the language used in the UI, the desktop background picture, etc.
I'm confused about the different tools I heard of to save a live distro into an ISO file that can then be used to burn it to a USB/CD: Remastersys (only for Debian/Ubuntu), MondoRescue, Mylivecd, Reconstructor, and relinux. There are possibly other tools as well.
I don't know yet if I'll for Ubuntu or Fedora (or possibly yet some other distro, but it's unlikely). Which tool would you recommend for this project?
