+      local_output_dir: Use regular file system local to the compute node.
+      There must be sufficient local scratch space to store entire output;
+      specify this with `outdirMin` of `ResourceRequirement`.  Files are
+      batch uploaded to Keep when the process completes.  Most compatible, but
+      upload step can be time consuming for very large files.
+    - |
+      keep_output_dir: Use writable Keep mount.  Files are streamed to Keep as
+      they are written.  Does not consume local scratch space, but does consume
+      RAM for output buffers (up to 192 MiB per file simultaneously open for
+      writing.)  Best suited to processes which produce sequential output of
+      large files (non-sequential writes may produced fragmented file
+      manifests).  Supports regular files and directories, does not support
+      special files such as symlinks, hard links, named pipes, named sockets,
+      or device nodes.
