The original default, minimum abbreviated hash length was 7. It dif- fers on newer systems, however. This breaks reproducibility, so set an explicit length. 12 hex digits should be good enough. Note: This sets only a minimum. With a high enough number of commit objects in the repository, Git could still decide to use a longer hash, again breaking reproducibility. 12 digits will hopefully pro- vide enough margin.
