Yes, I'm tracking DebianGIS from the beginning.
A few months ago I moved to Ubuntu, just for the same reason as you 
mention below ;-) and here I'm new for UbuntuGIS.
So, please, could you give little overview what have you done in Debian 
GIS for DebianGIS and UbuntuGIS integration?

Yes, but there are so many packages and - as I talk to Burgundavia and 
ogra in #ubuntu-devel yesterday - we need to decide a roadmap. We 
discussed my proposal and I will include it to UbuntuGIS wiki page 
tomorrow I think. In general, we need:
- to group pacakges in some logical meta-packages i.e. webmapping stuff
- define priorities between groups - meta-packages
- define priorities for packages insinde defined groups

Just a roadmap. Have you any suggestions?
Where to start, how to proceed in order to do best?

Definitely, agreed :-)

In fact, Debian is Ubuntu's father ;-)
BTW, who is the mother, hehe?

Sure, and we need to adapt it to Ubuntu. But we still need an adaptation 
roadmap. Next, we need to go further and work on new features for 
UbuntuGIS, I think so.

Certainly, I agree. Note, as I said in one of my posts, I'm not a MOTU 
or very experienced deb developer and maintainer, but I agree and I'm 
trying still to lower my own the learning curve of packaging ;-)

So, you propose to do it indirectly with help of DebianGIS repos.
 From my point of view there are some advantages but I'm not able to 
decide. Generally, agreed but I have one comment, that in some cases 
DebianGIS repos could be limiting us i.e. when we would want - 4xW ;-) -
to include latest versions of i.e. PostGIS or GDAL.

You mean MOTUs, right?
