Ubuntu 16.04 LTS Images
16.04 has landed. I expect we want to wait at least a month or two before releasing images, to avoid the initial bugs, but the work could start now-ish. The existing systemd support for ubuntu15 might just work, but at the very least we need to ensure that the service deps are correct and don't introduce startup races or deadlocks if bad stuff happens on boot (i.e. no net, slow net, etc). I think we should try to get the OpenStack ones within a couple of months... meaning I feel like those should be done by end-June. But since I have to do that part, we'll see how the priorities fall out.
Here's some of the highlights from the release mail:
The Ubuntu team is very pleased to announce our sixth long-term support release, Ubuntu 16.04 LTS for Desktop, Server, Cloud, and Core.
Codenamed "Xenial Xerus", 16.04 LTS [...]
The Linux kernel has been updated to the 4.4.6 longterm maintenance release, with the addition of ZFS-on-Linux, [...]
Ubuntu Server 16.04 LTS includes the Mitaka release of OpenStack, [...]
Ubuntu 16.04 LTS introduces a new application format, the 'snap', which can be installed alongside traditional deb packages. These two packaging formats live quite comfortably next to one another and enable Ubuntu to maintain its existing processes for development and updates.
