I have seen how you can use KNOPPIX to install Gentoo(which also installs Debian),...also I have seen Gentoo and Debian create Gentoo/BSD, and Debian/BSD hybrids...
I have also seen how SabayonLinux has made the use of Gentoo easy.
Here is the concept a Ubuntu/Gentoo hybrid:
Imagine first of all Ubuntu with Emerge...Image the ease of installation of Gentoo as found in Ubuntu..
It would require (I think) making Gentoo the foundation of Ubuntu as opposed to Debian. (or making the foundation a combination of Debian and Gentoo....utilize the best from both)
The current Debian based Ubuntu would and should continue to exist but if there are any developers, idealist, dreamers who think this would be a great idea...lets here from you...
Ubentoo....A Ubuntu/Gentoo hybrid
This is purely conceptual and I would like to hear opinions or even give birth to a new concept
