# Necessary for some CI/CD systems like Azure DevOps Pipelines which have incorrect ownership on the git checkout dir triggering this error:
#
#    fatal: detected dubious ownership in repository at '/code/sql'

# standalone script without lib dependency so it can be called directly from bootstrapped CI before submodules, since that is the exact problem that needs to be solved to allow CI/CD systems with incorrect ownership of the checkout directory to be able to checkout the necessary git submodules
