Do we need even more Linux distros? That’s a contentious topic, but if you’d like to make your own flavour of Fedora, see this guide to using Revisor, Fedora’s re-build application. With some intermediate Linux knowledge (and a spare few hours), you can customise Fedora DVDs with your own software selection and updates.
That is a nice idea, I might give it a shot when I have some free time.
It^A's the nLite/vLite for Fedora World!
