That's an interesting question - to clarify, if you have an automated 
"yum update" going on, and the nvidia drivers get updated, does that 
imply the currently-running system is destabilized, or do you just mean 
(as I always assumed) you simply have to reboot to get the new version 
active.

Well for my part it got me onto the mailing list (which I really knew I 
should be following anyway!) so quite aside from this issue I benefited 
by seeing all the other news I'd missed, such as your yum nvidia plugin. 
I tested that a bit while trying to figure things out yesterday and it 
seems to work exactly as advertised. Thank you so much for creating 
that. I keep finding old scripting snippets from our pre-ELRepo efforts 
to manage nvidia binary drivers, and it's so nice to be able to delete 
all that junk!
