Ah, great. And the rpms build cleanly from it. :-)

I don't mind having a script on the node that is coming back into the 
cluster that triggers when the node rejoins to head -1 all the files to 
sync, but detecting when a remote node rejoins and issuing the head -1 on 
all files on all other nodes to get the new node to sync is a bigger 
problem.

But if this has been fixed in 1.3.8pre6, then that's no longer a problem. 
:-)

Thanks.
