+# Use 'piped' SSH transfer method
+# For the reason noted above, file transfers using scp/sftp do not work, so
+# we force the use of the new 'piped' transfer method. This feature is not
+# available until Ansible 2.3, but neither is the following config option, so
+# this will be a no-op on older versions.
+# This role does not actually require this (yet), but it would be nice to use
+# the 'copy' module in the future.
