rsync - Dec 2007 - --link-dest

Clearly I'm missing something about --link-dest; I know it works because 
rsnapshot is doing the right thing on this system, but it's not on 
another system, and I'm trying to troubleshoot that.  The first step is 
to be able to verify that --link-dest works on it, but I can't even get 
it to work in an known-good environment --- no matter how I specify the 
args to it, it's copying the file rather than linking --- the b.0/x/y/z 
file should have an inode of 7439904, and it's getting a new one: 
7439910.  Hopefully someone can point me at the error of my ways...

The man page description of --link-dest states that rsync interprets the
path relative to the destination directory, so you need to pass
--link-dest=../b.1 .

That did the trick, thanks!
