Comment 9 for bug 1409639

the last of the patches to add systemd support in juju (including on vivid) has landed. There are a couple of caveats we need to look into though:

* vivid LXC containers on non-vivid hosts don't work correctly out of the box. This has an impact on local provider (I've been testing in a vivid KVM). See https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1347020
* vivid (and later) may be configured to boot with upstart (e.g. after an upgrade?). We are looking at adding a feature flag to support that use case (which I expect will be an uncommon one).
