I agree that rsync being stateless is a good thing. I have found it very
reliable and predictable for years. I certainly wouldn't change to unison
(which apparently is currently not maintained) just to speed up the file
Delta-transfer of the file list seems to make good sense for rsync,
especially for one-way backup involving lots of files. Is there any
chance that this will happen, or any way to gauge interest in this?
