 Hi,

 There's a code review in progress (http://reviews.vapour.ws/r/4286/)
 that will introduce a predefined action, "juju-run", which is part of the
 replacement for the current SSH-based juju-run.

+1 to reserving the juju* space just as we do with relations and such.

This is interesting. What's the semantics for this? How does juju-run
action work for machine level items?
