Kolla 1.0.0 has a fatal flaw in its design related to data containers. The details are outlined here:</div>

Our plan to rectify this involves taking what is in stable/mitaka and making it stable/liberty and placing 1-3 patches on top of stable/liberty to make it deploy the liberty version of openstack. These 1-3 patches include metadata like repo locations, upstream
tarball locations, etc. No actual code. This is a one time thing; in the future we will be following a strict bug-backport only policy.</div>

<div style="color: rgb(0, 0, 0); font-family: Calibri, sans-serif; font-size: 14px;">
Our options include:</div>
<div style="color: rgb(0, 0, 0); font-family: Calibri, sans-serif; font-size: 14px;">
1. make a megapatch diff of liberty vs mitaka and merge that, with a patch on top to fix the repos</div>
<div style="color: rgb(0, 0, 0); font-family: Calibri, sans-serif; font-size: 14px;">

2. Tag the tip of stable/liberty with liberty-early-demise, delete the liberty branch, then create a new stable/liberty branch from the tip of stable/mitaka</div>

<div style="color: rgb(0, 0, 0); font-family: Calibri, sans-serif; font-size: 14px;">
3. Tag the tip of stable/liberty with liberty-early-demise, and run git reset —hard origin/stable/mitaka outside of gerrit. Tonyb says our setup prevents non-fast-forwarded pushes so this might not be viable.</div>

What we want to avoid is jamming 1k+ patches through our CI system and having the core reviewers have to deal with acking all those patches, or overloading gerrit and breaking things there. </div>

I am far from a git wizard, and don't really know the best way to proceed, other than we must have a liberty 1.1.0 deliverable with our mitaka bits + liberty repo pointers. I'd really like to preserve history. What we need is for stable/liberty to be an
exact duplicate of stable/mitaka codwise, while also preserving history (which option 1 doesn't do).</div>

Can the Kolla community get an ack on the options from the Infrastructure team one way or another, so I can get the ball rolling on our end and sync up with Doug on the plan?</div>
