I couldn't have said it better. Thanks techne.
Indeed. It is feasible, and it would require extra-work, and as mentioned above it is not our number #1 priority.
Barbara was 99% edgy, Bea is probably still 90% edgy... Bianca will be less than that. Although future version of Linux Mint will be compatible with Ubuntu packages and repositories, we're introducing more and more differences and sometimes taking a different direction than Ubuntu.
It is possible to make a meta-package that would include all of Bea+Barbara changes and allow Ubuntu users to get a similar desktop, but it would require extra work... and at the moment I see more important things that need to be done.
If you look at the Kubuntu project, they have different ways to install their distribution on a computer:
- live CD
- alternate install
- kubuntu-desktop on top of Ubuntu
- upgrade from previous Ubuntu versions
We, as a project, only provide the live CD option. I know there is a need for the other options to be done, but we're still a very small team and before we address "different ways to do one thing" we want to make sure we're finished with making that "one thing" the best as possible.
Now, if somebody wants to take responsibility and lead one of these sub-projects, that would be great. But as far as I'm concerned the priority goes to Bianca (2.2) and after that to Linux Mint 2.3.
