Did you know you could pretty much install Ubuntu on Debian Sid? Now you do!
Well, yes and no.
Yes because I installed a set of Ubuntu packages on a (de)bootstrapped Sid Debian distribution.
No because the debootstrap actually installed Ubuntu packages, and the set of packages Ubuntu and Debian install at their base are actually quite similar.
If you diff the 2 debootstraps scripts (Ubuntu Gutsy vs. Debian Sid), you'll see very little difference between the 2. To make that work you have to alias the Debian Sid distribution to Gutsy otherwise deboostrap will fail saying it can't find the source distribution on the mirror.
On the CD I'm making, I'm using a custom distribution name, made off Ubuntu packages. With a quick hack to deboostrap, you can make debootstrap install Sid using Gutsy packages!
