If `safe.directory=*` is set in system config and you want to re-enable this protection, then initialize your list with an empty value before listing the repositories that you deem safe. ++ +As explained, Git only allows you to access repositories owned by +yourself, i.e. the user who is running Git, by default. When Git +is running as 'root' in a non Windows platform that provides sudo, +however, git checks the SUDO_UID environment variable that sudo creates +and will allow access to the uid recorded as its value in addition to +the id from 'root'. +This is to make it easy to perform a common sequence during installation +"make && sudo make install". A git process running under 'sudo' runs as +'root' but the 'sudo' command exports the environment variable to record +which id the original user has. +If that is not what you would prefer and want git to only trust +repositories that are owned by root instead, then you can remove +the `SUDO_UID` variable from root's environment before invoking git. |
