Permissions on symlinks in the absolute path of certbot-auto are ignored and only the canonical path to certbot-auto is checked. There could be permissions problems due to the symlinks that are unreported by this script, however, issues like this were not caused by our documentation and are ignored for the sake of simplicity.

The permissions are considered safe if the file is only writable by uid/gid < 1000. The reason we allow more IDs than 0 is because on some systems such as Debian, system users/groups other than uid/gid 0 are used for the path we recommend in our instructions which is /usr/local/bin. 1000 was chosen because on Debian 0-999 is reserved for system IDs[1] and on RHEL either 0-499 or 0-999 is reserved depending on the version[2][3].
