+Automatic installability checking
+
+<p>I've just finished deploying automatic installability checking for Ubuntu's development release, which is more or less equivalent to the way that uploads are promoted from Debian unstable to testing. See <a href="https://lists.ubuntu.com/archives/ubuntu-devel/2012-October/036043.html">my ubuntu-devel post</a> for details. This now means that we'll be opening the archive for general development once glibc 2.16 packages are ready.</p>
+
+<p>I'm very excited about this because it's something I've wanted to do for a long, long time. In fact, back in 2004 when I had my very first telephone conversation with a certain spaceman about this crazy Debian-based project he wanted me to work on, I remember talking about Debian's testing migration system and some ways I thought it could be improved. I don't remember the details of that conversation any more and what I just deployed may well bear very little resemblance to it, but it should transform the extent to which our development release is continuously usable.</p>
+
+<p>The next step is to hook in <a href="http://dep.debian.net/deps/dep8/">autopkgtest</a> results. This will allow us to do a degree of automatic testing of reverse-dependencies when we upgrade low-level libraries.</p>
