Comment 22 for bug 1384503

Thank you for the test case. Unfortunately Ryan is no longer available to work on this, so I'll unassign him.

Fixing this is non-trivial. I think any fix has a high risk of regression, particularly with the permutations of rsync versions that must interoperate. The full matrix needs to be considered and each permutation tested. Given that this is a significant amount of work, the compatibility issue with older versions will die over time, and 16.04 exists, I'm not sure it's worth our time.

This does not preclude any volunteer from taking this on, however.
