Staying away from infrastructure and toolchain changes is something I really
want to see for such a branch.

That would be stuff based on the java/osgi framework we are deploying so
hopefully it would not make problems for anyone else. I don't expect to much
problems with that.

With regards to the lifetime I don't see this as a several years branch fo our
product (thinking about oe-core for the next release). Obviously it is still
fine for other people to use it that long. The current stable branch is a good
example for this. It is still used and different companies/people are happy with
it having no updates at all for some time. :)

I would expect something else for the branch on top of the 2011-03 release. Some
more changes in the begining while fixing problems that poped up after the tag
was created but commits will slow down after some months.

Agreed.

Agreed as well. It gets a mess if we start fixing stuff in the release branch
only.
