/merge

I don't know exactly what the process is here. Since we already know we want to hotfix this for 23.06, do we target this at 23.08 then cherry-pick the commit, or do we target at 23.06 and then let the forward-merger take over @raydouglass?

[bdice]

LGTM but I'm not sure how to move this forward.

You can do either. Merging to branch-23.06 and letting the forward-merger merge into branch-23.08 is probably easier. That said, it looks like this PR branch was branched originally from 23.08 so it needs to be rebased before merging into 23.06. So six of one, half dozen the other in this case.

Edit: Actually, merging to branch-23.06 then forward merging will be cleaner. If you cherry-pick, the forward-merge PR will have conflicts requiring manual intervention.

[shwina]

OK, then I'll open a new PR targeting 23.06

[bdice]

@shwina FYI, I think the cleanest way to do this (without sending tons of GitHub notifications) is to rebase locally, force push, then change the target branch of the PR.

Actually with @bdice's help I'm going to finally figure out how to rebase correctly.
