I don't think Debian counts as a distro "with frequent, short-lifetime releases", though. Stating overall that we don't intend to support distro versions that the distro themselves doesn't support ought to be sufficient, shouldn't it? In general, my view is that if we bump up against any of these support-lifetime limits then we're being too eager to drop support for something from QEMU and we should prefer to retain support for a while longer. I like and think that it's important that QEMU as a project does not live on the bleeding-edge and require latest-and-greatest versions of its dependencies to build. thanks -- PMM
