# [PATCH 2/3] Add setup_new_git_dir() function 1 messages from 2007-07-22 to 2007-07-22. Participants: Johannes Schindelin. Thread: https://gitlist.dev/t/9149 ## Johannes Schindelin, 2007-07-22 18:56 Subject: [PATCH 2/3] Add setup_new_git_dir() function Message-ID: URL: https://gitlist.dev/e/Pine.LNX.4.64.0707221956010.14781%40racer.site ``` With the function setup_new_git_dir() you can reset the path that will be used for git_path(), git_dir() and friends. The responsibility to close files and throw away information from the old git_dir lies with the caller.
