See "scripts/repo_sync_manifest" which is currently being enhanced to do nearly everything needed to sync branches, versions, buildspecs, and cherry-pick in CLs as needed.

Don, what do you think the ETA is on that? I was planning on leveraging/stealing your work to implement syncing to manifests/ToT.

This landed today: https://crrev.com/c/1330170

It now supports everything except:

A) Cherry-picks defined inside a buildspec manifest.
B) "Local" cherry-picks (cros tryjob -p)

I plan to put it into production in the new "buildspec" builders I'm creating for firmware / factory.

Cool! I'm going to merge this into crbug.com/904926 because I don't think Initial Checkout really makes a ton of sense when Recipe is the one doing the checkout and it's updated out of band (via the ChOPs Recipe Builder). Sound reasonable?

Um... this is 904926.

But in general, yes. All of the sync stages should be merged into one bug.

I'm not sure what the other bug tracking the same thing happening in Recipes but as long as we have a bug tracking that Recipes impl, it makes sense to merge.
