Under what license is Ubuntu? Can it be legally modified and distributed?
I have made my own version of Ubuntu that I have customized using tools. I removed some application I didn't like, changed the login image to show my customized image, added the apps I like, changed other stuff etc.
The only thing I kept is the sources.list - this still goes to Ubuntu when I do the apt-get update && apt-get safe-upgrade
Is it legal for me to distribute my version? Or should I keep it for myself?
