Looking at some of the really basic systems, that are running Ubuntu (highly stripped) and tailored to their 'really basic systems,' and with the approval of Canonical and Mark Shuttleworth, I would almost venture to say that there is a place for not only those that want control (sinners such as we) or those that need control (hardware developers and other grievous sinners such as they... had to carry the sinning thing along), but, what I am proposing, is not that far out of possible (e.g. two different install iso's... one for newbie saints... and one for the Al Yankovich types (weird, wired and sinners)... Call one, "Welcome to the heaven of Ubuntu"... and the other "HELL-o"\|/"o. One would have the standard distro... and the other warning labels asking for your adult supervision signatory.
But, the other would contain what is needed (let's call it the 'Happy Valley' Ubuntu) and, a wild west drinking town of other options (use at your own risk and Mr. Shuttleworth will laugh his bum off at any support requests...) "No More Warnings" Ubuntu.
You say it can't, I still say it can.
I would just like to do it without having to clean up such a mess, before I make my own.
