converting from debian unstable to ubuntu?
 

I have been using Debian Unstable for about 18 months and I love it. I saw Ubuntu recently and was very impressed.

Does anyone know if it's easy to convert an existing Debian Unstable system to Ubuntu? Can I just change the apt-get sources and do a distupgrade? Or is that asking for a WHOOOLE lot of trouble? ;-)

I don't think so. Maybe you could change your sources.list to include the ubuntu repositories and install GNOME 2.8, then you could build and patch a kernel to be the same as the one shipped with ubuntu, then you could install and configure sudo, and by that time, you might as well re-install.
