HI David,

I'm sure you've found this bug by now,
https://bugs.launchpad.net/juju-core/+bug/1027876. In short we know
debug-hooks is something that needs to be implemented for feature parity.
The juju 2.0 milestone was supposed to be 13.04, but now represents a point
in the future (13.10 maybe) when a major version number (read, possibly
breaking change, or not as automagic upgrade) change will occur. I have no
information on when this feature is scheduled to be worked on at this time.

Cheers

Dave
