The problem there is that given that all 9.x packages have been already
pushed to the archive with ABI changes and so on, we *must* switch the
default kernel for wheezy to 9.x. I don't say it's a bad decision, but
I would have prefer to have some discussion about, it including the
possible consequences of such a choice, instead of getting to the point
of not having any other choice.
Now we have no choice than making a real plan for switching to 9.x
- We have to make sure users are using wheezy/sid with a 9.x kernel.
- We have to provide an upgrade path for users, including the best
moment to switch from one kernel to another in the release notes.
- The build daemons are going to stay with the 8.1 kernel up to the
release of wheezy. Will it work? Sometimes after they are going to
switch to a 9.x kernel, but they should still be able to build squeeze
packages. Will it work?
Who wants to work on addressing these points?
