1. Only mount points of kind @collection@ are supported.
-2. Mount points underneath output_path must not use @"writable":true@. If any of them are set as @writable@, the API will refuse to create/update the container request, and crunch-run will fail the container.
+2. Mount points underneath output_path which have @"writable":true@ are copied into output_path during container initialization and may be updated, renamed, or deleted by the running container. The original collection is not modified. On container completion, files remaining in the output are saved to the output collection. The mount at output_path must be big enough to accommodate copies of the inner writable mounts.
3. If any such mount points are configured as @exclude_from_output":true@, they will be excluded from the output.
h2(#symlinks-in-output). Symlinks in output
-When a container's output_path is a tmp mount backed by local disk, this output directory can contain symlinks to other files in the the output directory, or to collection mount points. If the symlink leads to a collection mount, efficiently copy the collection into the output collection. Symlinks leading to files or directories are expanded and created as regular files in the output collection. Further, whether symlinks are relative or absolute, every symlink target (even targets that are symlinks themselves) must point to a path in either the output directory or a collection mount.
