Oh sure, I appreciate that wheezy is getting towards then end of its lifetime - it's just a little bit inconvenient to break my development environment just as we enter 2.9 freeze ;) If everyone agrees that wheezy is no longer supported after 2.9 then I can look to upgrading, however my QEMU development is done on my laptop which is also setup for my day job so it's not a simple case of just switching the repository and running dist-upgrade to get me going again... ATB, Mark.
