"No, that can't be right, Ubuntu is based on Debian!"
And so is Knoppix. And so is Knoppix fork called Morphix that was used as a LiveCD builder for Ubuntu 4.10. I have irrefutable evidence of this, and I am surprised that no one on the Internet seemingly never mentioned that before.
That is not to say that Ubuntu is not based on Debian - it is. I am not trying to say that it does not come with its own packages and kernel, either. But it is _also_ based on Morphix, at least in LiveCD 4.10.
First, I'll share a few screenshots hinting at the similarities. Then I'll show you the solid proof I'm talking about. And then I'll just share a bunch of screenshots of old Linuxes just for fun!
GRUB and splash screens are not a smoking gun, but consider how similar Ubuntu 4.10 Live and Morphix 0.5 boot experiences are (both circa October 2004).
