Hi, so  -


Is an ops track session about dependencies - focusing on the
operational side (mysql, mongo, rabbit etc). I'd love to have some
developer centric folk in the room, though I'll be doing my best to
capture the ops constraints. My hope is to have a really clear story
about what we can and should depend on, and the cost of non-boring
tech, for our operators.

We don't need to do that. I've put some expanded thoughts together here:


I *think* that avoids the omg refactor-devstack thing, at the cost of
a small additional feature in pip.

Thierry says we're going to slot this into
or the followup after lunch - I'd like to pin it down more than that,
if we can.
