So that does work. Now I decided to install Ubuntu Natty (11.04), as it has the Cobbler package in it as well.

I played around with the preseed file until I got it as close as possible, and there are still problems due to network card weirdness (it seems to be re-initialized at some point, breaking everything).

In any case, Cobbler 2.1 is installed, and Ubuntu CDs import just fine. I’m also importing CentOS 6 right now. That worked fine as well.

So 2.1 > 2.0.11 even though 2.0.11 is newer.
