How to install Debian Testing... and why you might not want to

Packages in testing get updated at the times that they can and sometimes this messes with other packages. For example I had pithos installed this morning, in trixie. An upgrade removed a dependency so it had to go. In another day or 3 I will be able to install pithos again, no doubt. Running testing when release is within 9 months since sarge and this is the only issue I have seen. Since it resolves itself, I never saw it as a problem.
