Which fixed an OOM with unlocked files.
Debian oldoldstable is the oldest version of git that git-annex needs to
support, since it's used in the amd64ancient build. That has 2.30.
At this point, the only complication git-annex for an bug in old
versions of git is that git bundle was broken before git 2.31.
That prevents git-remote-annex from working with git 2.30.
