+On June 21st, 2022 1.17.0-rc1 was published and the location of the gitconfig file moved to a new location, [which required manual intervention](2022-06-23-1.17-breaking-episode-1). This change impacted a large number of Gitea installations because the docker image tag **latest** [was set to 1.17.0-rc1](https://mastodon.online/@hostea/108514134565401798) by accident. As a result, about 10,000 pulls per hour from the docker hub got the release candidate instead of the expected stable version.
+
+Unfortunately moving the git home directory in 1.17.0-rc1 was implemented in way that created a security problem. The [fix that was merged in Gitea](https://github.com/go-gitea/gitea/pull/20114) to fix it requires moving the gitconfig file and was released July 19th, 2022 in 1.17.0-rc2.
+
+This would have been a minor inconvenience if it only has an impact on adventurous people trying the release candidate in a test environment. But since all Gitea production installations based on the **latest** tag were inadvertently upgraded to 1.17.0-rc1, the admins who moved their custom .gitconfig will need to move it one more time when upgrading to 1.17.0-rc2.
+
+In 1.17.0-rc2, a custom .gitconfig must be moved manually to the [new git home directory](https://docs.gitea.io/en-us/config-cheat-sheet/#git-git) as follows:
+
+* Figure out the directory where `$HOME/.gitconfig` must be moved by [running the doctor](https://hostea.org/blog/gentle-introduction-to-the-doctor/):
+
+```shell
+$ gitea --work-path /app/gitea -c /data/gitea/conf/app.ini doctor 
+[1] Check paths and basic configuration
+ - [I] Configuration File Path:    "/data/gitea/conf/app.ini"
+ - [I] Repository Root Path:       "/data/git/repositories"
+ - [I] Data Root Path:             "/data/gitea"
+ - [I] Custom File Root Path:      "/data/gitea"
+ - [I] Work directory:             "/app/gitea"
+ - [I] Log Root Path:              "/data/gitea/log"
+OK
+```
+
+* Copy the `$HOME/.gitconfig` file to the **Data Root Path**/home (which is `/data/gitea/home` in the example above).
