I'm sorry for bringing this up here but I believe I wasn't around when this
discussion happened at the summit. To be honest, this strikes me as weird. I did
not expect image sharing to be a priority and I would really appreciate the
reasoning behind this. I'm a bit concerned by the impact, if any, this might or
might not have on the image import work.
I'd have voted for other topics so, I'm really curious to know the answer to the
above. Also, I'm sorry for not having been there.

Noticed you mentioned here the image sharing work won't impact the new import

The above seems to be exactly what we've done so far. Anything I'm missing?
In Mitaka, we started writing the contributors guidelines for Glance. I believe
the above should be put there. Thoughts? (I'm volunteering you :P)

Interestingly enough, I was going to propose to get rid of that section. I don't
think it's useful and often enough the reviewers listed in the spec are not the
ones actually reviewing the patches. I'm happy to discuss this on gerrit over a
patch. Oh, look:

These lite specs are expected to be filled in the `lite-spec` file in
Just want to make sure the process hasn't been changed here since Erno's patch
is still on review:

Not big deal but after looking at this list it seems the mid cycle might happen
a bit too early in the cycle. Thoughts? Is that on purpose? I'm good either way,
I just want to make sure we consider this.

I did a similar analysis in my summary email from Mitaka. Does the above
considers Stuart hiatus?
