Probablemente nunca; parece que la próxima versión de OpenJDK en la que trabajarán los porteadores de FreeBSD es la versión 11 , la próxima versión con soporte a largo plazo -.
Por supuesto, como menciona Kusalananda en su comentario, ¡no hay nada que le impida migrar OpenJDK 9 a FreeBSD!

etckeeper is a collection of tools to let /etc be stored in a git, mercurial, bazaar or darcs repository. This lets you use git to review or revert changes that were made to /etc. Or even push the repository elsewhere for backups or cherry-picking configuration changes. It hooks into package managers like apt to automatically commit changes made to /etc during package upgrades. It tracks file metadata that git does not normally support, but that is important for /etc, such as the permissions of /etc/shadow. It's quite modular and configurable, while also being simple to use if you understand the basics of working with version control.
Сам по себе Git не будет записывать метаданные, такие как разрешения, необходимые для правильного резервного копирования /etc
