Well, (Dr) Andrew "tridge" Tridgell and (Dr) Paul "paulus" Mackerras
wrote rsync whilst studying/working at DCS (aka CSIT at ANU), with some
input from Prof. Brendan McKay. Whether the "link-dest" option was added
as part of their work on it or not, I cannot say.

However, seeing that the 34,000-odd command-line options to "rsync" were
clearly not enough, I added the "--backup-dir" option (and a related
option or two) which we use in production here at DCS (aka CSIT at ANU) for
almost all of our backups.

So, sorry, can't help with link-dest, but we do not use it here at DCS
for our production backups, although someone here may well be using it
for their own purposes.
