OK, so this is mostly a writeup of things I noticed, when I notice them. No
order implied in the order of occurrence,

* You seem to be using sort of an older approach of the debian rules setup.
  I think you likely use a git tree as a source as well and I could imagine
  it making things simpler for you if you had the (in this case karmic) tree
  of us as a base and the rt stuff on top, then you might be able just to
  rebase whenever we change.
  From the quick look it seems like the rules are modified to support the
  approach of patching on the fly. Correct? Nothing wrong with that. Just
  trying to show up alternatives here.
  One of the options with our new layout is, that you can have all your
  configuration separately in a (for example) debian.rt...
* In the changelog I noticed a big jump in the release number in the middle
  of Karmic. Just curious why that happened.
* When building the package, the produced packages look ok. I understand the
  linux-rt-headers arises from the requirement to have unique naming and still
  trying to follow the usual approach to have that common header package for
  all flavours. Some of our topic tree packages use no common headers package
  there or are save by having unique ABI numbers.
  linux-headers-2.6.31-11-rt_2.6.31-11.154_amd64.deb
  linux-image-2.6.31-11-rt_2.6.31-11.154_amd64.deb
  linux-image-debug-2.6.31-11-rt_2.6.31-11.154_amd64.ddeb
  linux-rt-headers-2.6.31-11_2.6.31-11.154_all.deb

Overall the packaging looks reasonable to me, so I guess we should get together
on IRC next week and talk about uploading it. The things I noted down are stuff
to think of going forward and I believe Andy wanted to have a look at the new
flavour for Maverick. So we can probably talk together.
