Background: bitbake downloads git repositories during a build process and supports caching them locally (in form of bare repos in some user-defined directory). This prevents having to re-download them during the next build, and also it is a convenient mirroring/backup system in case the original URLs stop working. As far as I can tell (since I'm not a bitbake developer) the git pack-redundant invocation is one of multiple calls meant to improve storage (probably minimize disk usage) of the locally cached git repos. For reference, please take a look at the other git commands it's invoking [1], and at the commit messages of the commits that added these invocations [2] [3] [4]. If doing it that way seems wrong, I'll report the issue to bitbake upstream too. Maybe there is a better way to do whatever bitbake wants to do here? Thanks!
