+# migrated to another S3 server.
+#
+# Changes from upstream:
+# - The option is `services.minio-vendored`, since nixpkgs still reserves `services.minio` to
+#   show a removal message. The unit, user and paths are unchanged, so existing data keeps working.
+# - The package is defined here, as `pkgs.minio` now throws, and without `passthru.tests`, as
