Here is a note about the status of --no-tweak-hlinked for whoever it may
concern.  Wayne said at

https://bugzilla.samba.org/show_bug.cgi?id=4768#c5

that he does not plan to add this option to the official rsync.
However, I have found this option very useful in a number of backup
scenarios, so I plan to resume maintaining my own custom version of
rsync, which will support --no-tweak-hlinked and anything else I think
is useful.  This version of rsync will be available at:

http://mattmccutchen.net/rsync/

I will not advertise it on the main rsync list any further except when
it solves someone's problem.
