# Bundler runs git commands on git dependencies
# https://bundler.io/guides/git.html#local-git-repos
# git will check if the current user is the owner of the git repository folder
# This was included in git v2.35.2 or newer.
# https://github.com/git/git/commit/8959555cee7ec045958f9b6dd62e541affb7e7d9
# Openshift changes the effective UID, so this git check needs to be bypassed.
