### `allow_world_readable_secrets`

+Garage checks the permissions of your secret files to make sure they're not
+world-readable. In some cases, the check might fail and consider your files as
+world-readable even if they're not, for instance when using Posix ACLs.
Setting `allow_world_readable_secrets` to `true` bypass this
permission verification.
