I see a big difference between multiple releases like
stable/testing/unstable and a fork or parallel releases like Ubuntu.
In stable/testing/unstable you have releases with a fixed version that
can only split of from the main trunk. Any change to stable/testing
MUST be made special for the old version in stable/testing and forks
off the main developement on its own course. There is no developement
going on in stable/testing, just bugfixes. You often have to prepare
backports for patches from unstable to share fixes.
In Ubuntu you have a parallel version. You split of from the main
trunk but you follow parallel to it at a small distance. For every new
main version you want a new ubuntu version. Ubuntu versions aren't a
branch but rather a filter on top of the main release. The main
release changes, the filter remains constant (hopefully).
Branches don't work so well for ubuntu as you have to pull over the
changes from the main branch to the ubuntu branch on every
release. Which means (unneccessary) work.
