[CentOS] opennx wants to replace nxclient on all my CentOS 6 servers

Looks like opennx appeared in the extras repository some time recently.  
Because the extras repository is enabled by default, all of the servers 
where I have nxclient installed are showing opennx as available which 
will obsolete nxclient.

I went ahead and upgraded on my laptop but the resulting opennx 
installation didn't launch properly.  I'm now modifying my yum 
configurations everywhere to add exclude=opennx

Without diving into the merits of whether I should be using nxclient 
from nomachine.com or the open-source opennx, I'm concerned that I ended 
up with a broken NX client and I don't remember seeing an announcement 
that this software package was added to extras.  Is that information 
communicated via a mailing list that perhaps I'm not subscribed to?

thanks,
Greg
