Yes, I know. But what I was expecting was the behaviour I get on i386:
rsync should recognise that it can't use/recycle the file because it
is on a different filesystem and make a new copy. Source and
destination should be as identical as possible, no matter how
'useful' the data in the directory specified with '--link-dest'
is. Or at least I would expect an error message. As I mentioned
before, I am worried that the error code of the link system call is
only printed in verbose mode. I could imagine a dozen of horrible
things that could happen while rsync is running and it would be
important that the user gets a notice that something went wrong.
